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.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

"d.) carbon dioxide and hydrogen sulfide"
