bacteria and fungi are decomposers
B
they live soil and water
C

D

Explanation: 

Detailed explanation-1: -In photosynthesis, plants and algae use solar energy to take carbon dioxide (CO2) from the air and synthesize sugars. This process produces oxygen as a byproduct, which earth’s animals depend on to breathe.

Detailed explanation-2: -On their own, algae and cyanobacteria are not good or bad. They are organisms that are important to the earth because they produce the oxygen needed to sustain life. However, if too much algae or cyanobacteria grow at once or if they make toxins, they can harm people, animals, and the environment.

Detailed explanation-3: -Like most plants, many algae produce oxygen during the daylight as a by-product of photosynthesis. At night these algae consume oxygen, but usually much less than was produced during the daylight.
