Explain how algae is indirectly essential to consumers in ecosystems, for example, polar bears.

Polar bear are found in the Arctic region. The polar bear feed on fishes, insects etc.

The algae undergoes photosynthesis and produces food through this.The algae is a source of food for the fishes in water. The algae makes the fishes grow and develop after providing it with the nutrients needed to do so.

The fishes are then eaten by the polar bear. Without the algae the fishes may starve and the polar bear may starve to death too due lack of preys such as the fish. This cycle makes the algae a very important source of energy.
