Commensalism

                                     


Commensalism - Commensalism describes an interactive (symbiotic) relationship between two organisms, when one organism benefits and the other remains unaffected. Examples include whales and barnacles, sharks and remora fish, and trees and birds.



Explanation: A tree with a bird's nest is pictured above. This nest resembles the benefit that birds receive from interacting with trees. The relationship between a bird and a tree is commensalism since the bird acquires a new nursery, while the tree remains unaffected by the new assemblage.

Lichen

                              Lichen - Lichen is formed as a result of a mutualistic relationship between a fungus and an algae or cyanobacteria. The fungus provides the cyanobacteria/algae with protection and the algae/cyanobacteria use photosynthesis to provide the fungus with nutrients. Lichen is plant-like in appearance and slowly branches across rocks, walls, and tree bark. Although it doesn't have roots, lichen also feeds off of dead matter as another source of nutrients. Explanation : Lichen is pictured above. Its green pigment helps with photosynthesis and comes from the algae/cyanobacteria. The fungus provides a both a physical body and protection for the algae/cyanobacteria.

Adaptation of an Animal

                                    Adaptation of an Animal -  An animal's ultimate goal is survival (avoiding extinction). This requires a species to have techniques for obtaining food and water, successfully reproducing, and protecting themselves from abiotic and biotic conflicts (like predators or harsh climates). An animal adaptation is any physical characteristic or behavioral habit that benefit's an animal's odds of survival. Examples include protective shells, colorful or bland markings, long necks, thick fur, larger ears, and extra bones. Explanation : A turtle is pictured above. This organism has adapted to its environment by developing permanent armor for predator and heat protection. When threatened by carnivores or heat prostration, a turtle hides in its tough shell to avoid confrontation with either of these conflicts. Its shell is also used to camouflage...
