What Is Symbiosis?By: April and Katlyn

Symbiosis is a close and long-term association between two or even more species.

Different Types of Symbiosis

Parasitism…A symbiotic

association in which one organism

benefits and the other is harmed.

Mutualism...A symbiotic

relationship in which both organisms

benefit.

Commensalism…

A symbiotic relationship in

which one organism benefits

and the other is unaffected.

Example of Mutualism

One example of mutualism is an ant, a butterfly caterpillar, and an acacia. The acacia feeds the butterfly caterpillar. The butterfly caterpillar has nectar organs that the ant eats from. The acacia gets protection from the ant.

Example of Commensalism

One example of commensalism is a whale and barnacle. The barnacle gets on the whale and gets to ride on it as the whale swims. The whale is unaffected.

Example of Parasitism

One example of parasitism is a dog and flea. The dog gets bit by the flea and the flea gets blood.
