Question

The giant green sea anemone of the Pacific Northwest coast consists of a cnidarian and alga. The algae performs photosynthesis and shares some of its carbohydrates with the cnidarian. A cnidarian provides the algae with some carbon dioxide and ammonia. This is an example of __________.

Answer 1

Mutualism

Step-by-step explanation:

Mutualism is an ecological association between the organisms of two different species wherein both the organisms are benefited and none is harmed.

In the given example, the alga obtains CO2 and ammonia from the associated cnidarian while cnidarian obtains organic nutrients from the photosynthetic alga. Since both the sea anemone and algae are benefited by the association, it represents the example of mutualism.
