by eating
C
through their gills
D

Explanation: 

Detailed explanation-1: -As autotrophic organisms, algae convert water and carbon dioxide to sugar through the process of photosynthesis. Photosynthesis also generates oxygen as a byproduct, contributing to the survival of fish and other aquatic organisms.

Detailed explanation-2: -Phytoplankton. Phytoplankton, literally “wandering plants, ‘’ are microscopic algae that float in the open water and give it a green appearance. They carry out photosynthesis using carbon dioxide that is dissolved in the water and release oxygen that is used by the bacteria and animals in the pond.

Detailed explanation-3: -Phytoplankton, better known as algae, is present in all lakes and ponds. While more than 30, 000 species of algae are known to exist, we generally only become aware of it when it reaches nuisance levels that negatively impact aesthetics, recreation, water quality and ecological balance.
