Which of the following is considered assimilation in the carbon cycle?

a. the respiration of a animal
b. a factory burning fossil fuels
c. a plant absorbing carbon dioxide during photosynthesis
d. fossil fuel deposits

C. A plant absorbing carbon dioxide during photosynthesis

Explanation:

Carbon assimilation occurs when  inorganic carbon (carbon dioxide) is converted to organic compounds by living organisms such as plants.

Let's analyze each choice;

The respiration of a animal - Respiration

A factory burning fossil fuels- Combustion

A plant absorbing carbon dioxide during photosynthesis- assimilation or fixation

Fossil fuel deposits - from decay of dead organisms and waste products.
