What Is Mutualism?

Mutualism is when both species working together benefit. Like, the Oxpecker and the Impala. Oxpeckers eat the insects on the Impala's back. The Oxpecker gets a meal, while the Impala has the relief of no bugs on its back.

What is Parasitism?

Parasitism is when two species work together when one benefits and the other is hurt. Like the cowbird and some other birds. The cowbird lays eggs in another nest to live on. The other birds eggs fall out of the nest when the cowbirds hatch.

What is Commensalism?

Commensalism is when two animals work together. One is helped, one is unaffected. Some birds fly alongside army ants. Insects get pushed out of the way as the ants travel. The bird goes and eats the shoved insects.
