WEDNESDAY: Predator/Prey Relationships

10/9/2013

Today, students learned about the predator/prey relationship between animals. Students were able to connect to real life scenarios and were able to identify the teeter-totter effect that always exists in different ecosystems. They learned that everything is connected and one small change can cause many things in an ecosystem to change.

LEARNING INTENTION: To learn about different predator/prey relationships and how changing one thing can cause a change within the ecosystem.

HANDOUTS:

In-line skating ($7.50)
Soap Stone permission forms and waivers ($45)

1.) MATH 6:

Quiz on multiples and factors tomorrow.
Complete String Art Activity and make sure you answer the 4 questions on pg 77 of your math textbook.

MATH 7: Any assigned questions.

2.) POST A RESPONSE:

Using your organism as an example, list at least one predator/prey relationship.
Assume that all of the grizzly bears you see in the video live in the Khutzeymateen Valley. If we were to add another 50 grizzly bears to this area, what do you think would happen to the number of prey (food) available?
Relate this to your animal and explain what would happen if you were to increase the population substantially.
What would happen to the number of prey?
What do you think would happen to the population of your organism?
Think about these questions carefully and explain using as much detail as possible based on what you learned today. What would happen in the short-term and the long term.
I can't wait to read what you all have to say!

for the Mountain goat the Bear is one of its predators and if you increase the population to much three will not be enough food for all of them and a good amount of them Will die from starvation and for long term very Little of them Will survive and because they need lot of water and not amount of water for any left to survive

My wound be an Bald Eagle and its prey the Fish.

and if u add 50 more bears their wound be to many and their food would run out and they wouldn't get enough nutrition and after a while they would probably die. if I were to increase the number of Bald Eagles their would not be enough fish or then to eat and not enough o the other animals they eat so that would probably decrease so types of their prays population ad their would be to many f the organism (bald eagles).

My organism is the black mamba. If 50 more black mamba came in it's ecosystem, they would run out of elephant shrew which is one of their main source of prey. If 50 more came in the same area they would also be fighting for other prey and many would die of starvation.

Ok for the Great White Shark you could do shark vs tuna who will win the shark of course. Say there is 457 in the ocean and there is the right amount of food for those sharks all kinds. What would happen if you added 53 more sharks they would end up eating each other and they would fight for space to live. The numbers of food will go down until there would be know more sad face. The the shark population will go down slowly.

For the blob fish it would be blob fish vs kellen irby. If there was 100 Kellen irby in the ocean, and only 20 blob fish, they will last some time. But if you threw in 50 blob fish, the population will drop super fast.

For Hedghog, one of their predators is the Europeon Owl. The reason for this is because hedgehog bones are commonly found in its pellets. If this owl speices keeps eating the hedghogs there would be no more hedghogs. And if there is not enough food and water for the hedghogs to all share, they will all die off. And then if there is no more hedghogs for the owls to eat. The Europeon Owls will die off.

quite true but the europeon owls would feed of the dead hedghogs to.

SAM

That is very true Cloud Barston! But all the dead hedghogs will eventualy be gone. Wich will slowly kill down the Europeon owls.

for a monkey a predator would be lions, cheetahs and leopards. these predators only want the monkeys for their meat and if they as in the predator does not get the meat then the predators will die off. and the overpopulation will cause the food chain to because unbalanced.

cloud barston

do these monkeys live in the savanna? if not know there was a type of lion or cheetah that lived in the jungle.

My organism is the african grey parrot. It eats berries and fruit, so it's a vegetarian. The only meat in its diet would be small snails and beetles. If more african greys came to the rainforest, there wouldn't be change to their diet, but it would be very different there because of the loud squaking noise that the parrot makes. Even though an african grey doesn't eat much meat, the amount of african greys would be a lot bigger. The amount of food would not be much different, because the plants always keep growing.

If you added 50 grizzlies to the amount already there at the river, there would be way to many to survive. As you saw in the video, the bears were already fighting for what prey there was. Even though they also said that there were tons of salmon in the river, they are hard to catch.

the predator for giant anteaters is pumas and leapords. if you put in 50 more anteaters into one area they would eat all the ants then they would die because lack of food. then the pumas and leapords would eat all of the dead anteaters then they would have no food source.

My organism is the Box Jellyfish. One of the prey are fish. If there were too many Jellyfish in one ocean, the fish would be all gone and we wouldn't be able to enjoy it like the other jellyfish. Next, the Box Jellyfish would die because of no food or wander to another place.

For the thorny devil its predator are flying birds such as the brown falcon. And if the brown falcons keep eating all the thorny devils, along with all its birdy friends, the ant population will increase by thousands because thorny devil eats only ants. Then all the ants will eat are food.

If 50 more bears come to the ones that are already there will be bearly any food and the bears will fight over it. Then the bears will attack each other and might kill an eat another.

My predator is the killer whale. The killer whales prey are small fish, and bigger fish, the killer whale can even eat the great white shark. If there were too many killer whale in the sea, the killer whale would start eating each other. And if the killer whale started eating each other, then the killer whale population would go down by a lot. Some humans eat whale blubber, so this would also affect them. As this happens, the fish that the killer whale used to eat, would be overpopulated.

If you added 50 more grizzly bears to the ones already there, the grizzly bears would be overpopulated, and not enough fish and prey for the bears. Then the bears would start eating each other, and the bear population would go down.

My animal is going to be a red fox prey is rabbits
And if you have like 20 foxes the amount of food they will have will shrink because of all of the foxes eating them and the rabbits just can't repopulate just like that it will take time to do that but the red foxes just keep eating them.

One Of the prey that leopard geckos feast on is crickets. If you were to add another leopard gecko to the population your outcome would differ weather it's a female or a male. If it where a female with another female nothing would really happen except lack of food not any fighting if it where a male and a female they would fight well at least the male would because males are more aggressive and also lack of food. Lastly male and male, they will fight to the death no matter what. With male and female they will breed so the population will get bigger.

The spider monkeys predator is the jaguar,raptor owls,puma,giant snakes. The spider monkeys prey is red beans,juicy fruits, and plants.

SAM

So are you saying that there is no living meat prey that the Spider Monkeys eat?

one hunter and hunted relation ship is deer and humans
if there were 30 humans in one area and the there was just enough deer if 20 more came there would not be enough for every one. so eventually people would start to fight for the food but this would not happen right away it would take awhile, people would probably start moving away again though so the deer would come back(most likely)

If you were to add 10 more portuguese man o war it would decrease the amount of small fish and increase the amount of painful stings. But it would help the turtles because they eat the portuguese man o war. once all the small fish are gone they probably wouldn't eat each other but die off because they float on top of the water so their tentacles that are in the water can extend to 30ft to grab small fish for them to eat.

If you added 50 Siberian tigers to 1 area then they may run out of food because the number of prey may not meet the needs of all the tigers. Also, the tigers would probably start to fight each other for the prey so the population would probably get smaller.

For a zebra predator would be a lion.Lion eat the zebra.Lions and zebras have an odd relationship. Odd by our standards, normal for the wild. It's safe to say it's obstacle, and one party.

NARWHAL Has 4 preys. Fish, Squids, Shrimp, And Nemofish.
The Main Prey It Finds Commonly Is The Fish And Shrimp But Sometimes Its Hard For The Narwhal To Find Squids And Nemofish.

NARWHAL Has 3 Predators. Killer Whales/Orcas, Whales *Due To Its Size*, And Swordfish Sometimes. The Narwhal Likes Swimming Slow And They Swim In Groups But When They Have a Predator Chasing After Them They Swim FAST.

I Think Each Of The Bears Will Fight For This Single Prey Because There's One Prey And 50 Predators. Then Most Of Them Will Die. But If You ALSO Add Another Few 50 Then It Would Be Equal If They All Get Their Own. Now Here's Another Example For The Narwhals. Since There Are LOTS Of Preys As Just Fish Then The Narwhal Will Be Able To Catch Them Fast. Depending How It Competes With Other Narwhals But If We Add Like 75 More Narwhals They'd Be Struggling Because Of The Low Amount Of Preys. And The Predator Of The Narwhal Will Get LOTS AND LOTS of Food. Then The Population Will Grow Smaller And Smaller As It Continues. That Was A Lot Of Typing. (Word Skills?)

1.) The Crystal Jellyfish and the Red Lions Mane Jellyfish
2.) All of the grizzly bears would slowly starve since there wasn't enough food, and to valence it out they would eat eachother, but by eating all the surrounding prey there'd still be none left, and same goes for the Crystal Jelly
3.) All of the prey would be eaten and they wouldn't have enough to create more prey, and by doing so the predators would have to eat something else or simply starve.

My animal is the penguin which is the prey and the walrus is the predator because it eats penguin.
If there were 50 walruses and lots of penguins and you added 100 more walrus they would all fight for the food until almost all of them are dead and all the penguins are to. So really they would make two species go extinct. If they don't all die then all the penguins will be gone and they will.

I think would happen to the prey would be bad. Because there are a hole bunch of killing hungry bears out there and they will kill so I think the thing that will happen to the prey is that there wont be as much of them on earth any more and more of a chance of that speecies going ecstink . And yea that is what I would think would happen.

A Mountain lion attacks a little mountain goat by the neck and kills it.

If there too many Mountain lions the population of the prey will rapidly decrease considering that they hunt lots every day. Also the number of lions will decrease to because the preys will be a compitition of killing.

The seal elephant (predator) attacks and eats small squid (prey).

If you add 50 more seal elephants to one area then they would fight to the death even more because there will not be as much food and when there is not enough food the food web gets destroyed. If that is not enough there would for a little while be so many elephant seals but when time goes by and there is no more food the elephant seals will start to die and if all speacies start to die we will not have any food left witch means no more human life on earth not any life on earth!

I think that if the prededorse population expands then they will eat all of the prey. so that prey wouldent eat their prey so that preys population expands and it starts all over again.

panda man

10/10/2013 07:49:40 am

if the leopard were to increase their population so that they could eat more what would happen to the food chain? the pandas population will be wiped out and the food chain would become unbalanced thus the leopards would die shortly after.
