Symbiotic Relationships of Native Animals of the Boreal Forest
Mutualism- Mutualism is a symbiotic relationship between individuals of different species in which both individuals benefit from the association. An example of mutualism in the boreal forest is Algae and Fungi: Fungi decomposes dead animals which puts nutrients back into the earth. This helps algae to grow stronger. Algae returns the favor to fungi by creating photosynthesized food for it so it can keep growing and doing its job.
Commensalism- Commensalism is a symbiotic relationship where one organism benefits and the other neither benefits nor is harmed. An example of commensalism in the boreal forest is a tree and a squirrel the tree supplies the squirrel with nuts to eat and the tree is not effected in anyway. - Parasitism- Parasitism is a symbiotic relationship in which one organism benefits while the other is harmed in a negative way. An example of parasitism in the boreal forest is Forest Tent Caterpillar and plants. The caterpillars are eating the leaves off of trees and plants, destroying them. Meanwhile, the caterpillars are prospering because they get more food so they can reproduce, while the trees and plants are getting destroyed and dying. This causes over-population of the caterpillars while the trees and plants are "under-populating".
