Answer 1

Answer:

C

Explanation:

Algae is releasing oxygen in a given area (pond water) and absorbing CO2 from the pond water.

An ecosystem includes all of the living things (plants, animals, and organisms) in a given area that interact with each other, as well as the non-living environments (weather, earth, sun, soil, climate, atmosphere) that surround the living things.
