Answer:

''The biological importance of green algae''

Explanation:

There is a huge biological importance of green algae because green algae provides oxygen as well as food to the marine animals. The equilibrium in the ecosystem is maintained by the green algae, if green algae is removed all the marine animals die due to no availability of food for the marine animals that feed on these algae. It also helps in maintaining the health of the marine ecosystem because algae are absorbed carbon dioxide that is released by fishes and also provide oxygen to the marine animals present in water.
