Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each.


Competition: Competition is when two or more organisms use a common resource for supply. It sometimes results in a reduction or one or both of the competitors. Competition can occur among members of the same or different species. An example of this is bluebells vs. poppies for the bee's pollination. 

Commensalism: Commensalism is occurs between individuals of two different species where one benefits from the other without harming the second one. An example of this is trees and birds because birds uses trees to build a nest but they don't harm the tree. 

Mutualism: Mutualism is a relationship between two organisms that both benefit from each other. An example is a butterfly and a poppy because the butterfly drinks the pollen from the poppy.

Predation: Predation is where an organism acts as a predator and catches and feeds on another organism. An example is stinkbugs eating a caterpillar.

Parasitism: Parasitism is when an organism benefits from another organism but hurts or injures its host. An example is tapeworms and their vertebrate hosts.
