Animal Relationships. By: Stephany Chavez. Forest. Mutualism - certain ants nest inside the plant's thorns. In exchange for food and shelter, ants protect trees from attack by herbivores and competition from other plants.

Mutualism- Sloth hairs are grooved, which allows algae to easily take hold and grow on the sloth's fur. This camouflages the sloth and allows the algae to get closer to the sunlight.
Parasitism- A parasitic wasp preys on fig wasps, drilling a small hole into the fig and using her long ovipositor to inject an egg near a developing fig wasp larva, which will be consumed by the parasitic larva after it hatches.
Commensalism-Flower mites which feed on pollen hitchhike from one flower to a fresher one by climbing into the nasal passages of hummingbirds and disembarking when carried to a better flower.
Scavenger-earthworm is a scavenger in the rainforest. It eats dead/dying leaves and plants.
Predator/Prey- bear and fish. Bear hunts for a fish in the river and the fish is being hunted by it.
Decomposers-Fungi are the great decomposers of the rainforest.
After the tree dies, the fungi must decompose it before these nutrients become available for other plants.
Competition-Assassin bug in the rainforest eats the ants.
Mutualism- Fiddler crab burrows aerate the roots of Spartina, providing essential oxygen to the plants, while the nutrient-rich waste created by mussels provides Spartina with nitrogen. In turn, the Spartina mixes the soil, provides a surface to which mussels can attach, and provides shelter and food to the fiddler crabs.
Parasitism-Isopods have adapted strong suckers, flat bodies, and sharp jaws used to attach to their host (fish).
Commensalism-Clownfish live in the stinging tentacles of sea anemones. They are coated in mucous, which protects them from the anemone's stinging nematocysts.
Scavenger- Sharks eating dead or wounded fish.
Predator/Prey- killer whales eat cod
Decomposer- bacteria and fungi, are what break down the dead organisms minerals and nutrients from organics and recycling them back into the food web.
Competition- Water Angler fish compete with each other for food.
Mutualism-Pollination of flowers by honey bees
Parasitism-A flea is a parasite on a coyote. The flea benefits by drinking the coyote's blood, but the coyote, by losing blood and acquiring discomfort and potential disease, is harmed.
Commensalism-Moss growing on trees benefits by being raised above forest floor competition, while the tree doesn't get much out of the deal either way.
Scavenger-Many large carnivores that hunt regularly, such as coyotes and mountain lions, will scavenge if the opportunity presents itself.
Predator/Prey-Scorpions (predator)/ insects (prey).
Decomposer-fungi on plants or a carcass
Competition-A coyote and another coyote will fight for food in the desert.
