What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one species benefits while the other is neither helped nor harmed.

Front

Provide an example of commensalism.

Back

An example of commensalism is barnacles attaching to a whale; the barnacles benefit by getting a place to live, while the whale is not affected.

Front

What is parasitism?

Back

Parasitism is a type of symbiotic relationship where one species benefits at the expense of the other, which is harmed.

Front

Give an example of parasitism.

Back

An example of parasitism is a tapeworm living in the intestines of a mammal, where the tapeworm benefits by absorbing nutrients while harming the host.

Front

What is the difference between mutualism and parasitism?

Back

In mutualism, both species benefit, while in parasitism, one species benefits at the expense of the other.
