What organisms are scientists using to eat carbon dioxide?
a.
e. coli
c. lichen
b. cyanobacteria
d. algae

The correct answer is- b) Cyanobacteria ( also known as blue green algae).

Cyanobacteria ( blue green algae) are the aquatic, photosynthetic bacteria that utilize carbon dioxide and water in the presence of sunlight to produce  food ( glucose) and release oxygen in the environment.

This process is known as photosynthesis.

They use a light harvesting green colored pigment called chlorophyll- a, which is present in them.

Thus, scientist use cyanobacteria to eat carbon dioxide.
