2.  Mutualism- Both animals benefit.  A leaf cutter Ant lives underground and it helps fungus.  A bee and a flower. A bee sucks the nectar out which lets the flower live longer and let it reproduce.  A bird and a worm. The bird eats the worm, and the worm gets to reproduce.

3.  Parasitism- One benefits, other is harmed  A leach and a hog. The leach sucks the blood and the hog loses blood.  A Monkey and fleas. The fleas get over the monkey and just keep growing.  A deer and a cheetah. The deer is getting hunted b the cheetah, and the cheetah won’t stop until it catches the deer as its prey.

4.  Commensalism- One organism benefits, other isn’t harmed.  A Monkey and fleas. The fleas spread everywhere, but other monkeys come and pick off the fleas and eat them.  A hippopotamus and flies. The flies swarm all around the hippo, but the hippo doesn’t care for the flies.  A Flicker and a cactus. The flicker makes a home in the cactus, and the cactus just stays there.

5.  Scavenger-One organism eats other dead organisms.  A fly eats dead organisms.  A Wildebeest kills an organism, then saves some meat for the next day.  A maggot finds a dead organism, lives inside it and eats all of the fat and nutrients from the body.

6.  Predator-Prey-One hunts, the other is hunted  A lion and deer.  A cheetah and hog  A bird and a worm.

7.  Decomposer-Breaks down dead organisms.  Bacteria  Flies  Maggots

8.  Competition- 2 organisms are fighting for the same thing.  2 lions are fighting for the female lion.  A fly brings back a dead fly and dances around it to see if the mate wants him or not.  2 cheetahs fighting for the same piece of meat.

9.  Mutualism-Both organisms benefit  Mosquito and a hippo. Mosquito sucks out blood and fat, and hippo gets veins cleaned.  Plover fly and crocodile. The plover fly flies into the crocodile’s mouth, and the fl cleans all of the dead meat stuck in the crocodiles teeth.  Leaf cutter ant and fungus. Fungus grows on leaves and ant cleans off leaves.

10.  Parasitism- One organism benefits, other is harmed.  A Gorilla and a monkey. The gorilla will chase the monkey down, until it captures or kills it.  A Frog and bugs. The frog eats the bugs which make the bug population go down.  A cicadas and trees. The cicadas lay there eggs in the tree and when the eggs hatch, they dig through the trees roots and cut every root.

11.  Commensalism- One benefits, other isn't harmed  An insect lays eggs in the sloth’s waste.  A poison dart frog and the virmliliad. Frogs use leaves as shelter to rain.  A Dung beetle and flies. The fly receives nutrients and shelter from the dung.

12.  Scavenger-Organisms that eat dead organisms.  A vulture eats any dead organisms it can find.  A Locto monkeys will also eat dead organisms or meat.  A Toucan will eat some type of dead organisms, but not very many.

13.  Predator-prey- Predator hunts, prey gets hunted.  A Panther hunts down other types of organisms, usually that are smaller.  A chameleon will hunt down certain types of bugs.  A jaguar hunts any type of possible organism.

14.  Decomposer-breaks down dead organisms  A Termites break down dead organisms.  Bacteria breaks down dead organisms  And even some species of insects break down dead organism for many reasons.

15.  Competition-when organisms fight over same desirables.  Jaguars will fight for the same mate.  Panthers will try to impress the mate to see who she picks to be her mate.  And Monkeys compete for better trees with more fruit.

16.  Mutualism- Both organisms benefit.  Penguin fathers watch there babies.  Polar bear and arctic fox. Polar bear kills organism and fox eats meat left after.  A Caribou eats shurbs and they spread it through feces.

17.  Parasitism- One organism benefits, other is harmed.  A polar bear and a penguin. The polar bear stalks the penguin.  A Mosquito and a caribou. The mosquito sucks the blood, and the caribou gets a rash.  A Caribou and tapeworms. The tapeworms have a place to live, but there slowly killing the caribou.

18.  Commensalism- One benefits, other isn't harmed  A caribou and arctic fox. The caribou cleans snow, and the fox has a place to walk.  Polar bear and penguin. Polar bear cleans snow up, and the penguin is able to walk in that line of clean snow.  A caribou and a penguin.

19.  Scavenger- eats dead organisms  A caribou will eat dead organisms  A polar bear will eat some dead organisms  A arctic fox will only eat some type of dead organisms.

20.  Predator-prey-Predator hunts, prey gets hunted.  A caribou and dead organisms.  A polar bear and penguins.  A Arctic fox and some land animals.

21.  Decomposer-Breaks down dead organisms  Bacteria  Fungus  Termites

22.  Competition-fight over desirables  2 caribous fight.  2 polar bears fight for food to survive.  2 penguins fight for a mate.

23.  Mutualism-Both organisms benefit  A clownfish and sea anemone.  A eel and octopus. Octopus kills, and eel eats some food.  A Fungi and algae.

24.  Parasitism-One benefits, other is harmed  Eel and fish. Eel kills and fish dies.  Whale and krill. Krill's die because whale swallows them whole.  Shark and fish.

25.  Commensalism-One benefits, other isn’t harmed.  A Clownfish and a anemone. Clownfish lives on anemone. And anemone gives shelter and safety to Clownfish.  A Shark and a remora fish. Fish cleans sharks bottom of any diseases.  A Shark and a human. A shark can smell blood from the human, and the person just watches the shark.

26.  Scavenger- eats dead organisms.  Dumpster shark  Remora Crab  Water Beetle

27.  Predator-prey- Predator hunts, prey gets hunted.  Shark and other fish  Eel and anything small that swims by its home.  Octopus and larval crabs.

28.  Decomposer-breaks down dead organisms.  Bacteria  Plankton  Fungus

29.  Competition-Fight over same desirables.  Sharks fight over mate.  Eels fight for hole or home to live in.  Octopus fight over food.

30.  Mutualism-Both benefit  Crab and Algae  Goby and Shrimp  Shrimp and Plankton

31.  Parasitism- One benefits, other is harmed  A Fish and Minnesota sea grant  A Sea anemone and certain fish  A Whale and krill. 

32.  Commensalism-One benefits, other isn't harmed.  Clownfish and sea anemone.  Shark and baby shark.  Octopus and crab.

33.  Scavenger- eats dead organisms.  Plankton  Shark  Whale

34.  Predator-prey- Predator hunts, Prey is hunted.  Shark & dolphins.  Whale & Krill  Eel & small types of fish.

35.  Decomposer- breaks down dead organisms.  Bacteria  Fungus  Plankton

36.  Competition- will fight for same desirables.  Sharks will fight for food.  Fish will fight for same mate.  Eels will fight to see who gets to live in the cave or hole.

37.  Mutualism- Both benefit  Hawk and a snake  Scorpion and a Lizard  Flowers and Honey bees

38.  Parasitism-One benefits, other is harmed  Snake and mouse  Snake and lizard  Scorpion and cricket

39.  Commensalism- One benefits, other is not harmed.  Holly shrub and bush  Snake and scorpion  Hawk and a armadilllo

40.  Scavenger-Eats dead organisms  Scorpion  Spider  Certain types of lizards

41.  Predator-Prey-Predator hunts, Prey gets hunted.  Snake and rat  Scorpion and cricket  Hawk and small lizards.

42.  Decomposer-Breaks down dead organisms.  Termites break down dead organisms.  Bacteria  Fungus also break down dead organisms.

43.  Competition- 2 or more organisms fighting for same desirables.  Snakes fight for a home.  Scorpions fight for food.  Lizards will fight to see who gets to stay where.
