Predation, Mutualism, Commensalism, or Parasitism
-
Commensalism Commensalism is a relationship between two living organisms where one benefits and the other is neither harmed nor helped.
-
The clownfish lives among the forest of tentacles of an anemone and is protected from potential predators.
-
Some birds live among cattle to eat the insects stirred up as they walk. One example are egrets who hunt for insects near a grazing animal's mouth.
-
One animal attaching itself to another for transportation such as barnacles attach to shells or whales or a shrimp riding on a sea slugs.barnacles on whales tail and clamshrimp riding on a sea slug
-
One species uses a second organism for housing such as small mammals or birds that lives in holes in trees or orchids which live in trees.Orchid in rainforest Venezuela
-
Parasitism One organism, usually physically smaller of the two (the parasite) benefits and the other (the host) is harmed
-
Ticks and fleas that live in a host animal's fur bite the animal and drink its blood are parasites.
-
Insects such as mosquitoes feeding on a host are parasites.
-
Vines such as Kudzu growing on Trees
-
Tomato Hornworm with Wasp Eggs
-
Tapeworm or Hookworms living in Host's Gut
-
The roots of the Owl Clover are partly parasitic on the roots of other desert wildflowers.
-
Mutualism Both species benefit from the interaction.
-
Flowers and their Pollinators (examples: Bees and hummingbirds gather nectar and spread pollen.)
-
Birds and mammals eatberries and fruits while the plant benefits by the dispersal of it seeds.
-
Algae and Fungi > Lichen - Alga gets water and nutrients from the fungus and the fungus gets food from the algae.
-
Cleaners eat insect pests from the skin of animals. (ex: Egyptian plover cleans giraffes and buffaloes)
-
Many herbivores such as cows, sheep, deer, horses and rabbits depend on bacteria that live in their stomachs to break down the plant material.
-
Coral Reefs- The corals get food and the algae get protection.
-
Predationone eats another (Herbivores eat plants. Carnivores eats animals.)
