Question

1. if the rate of combustion in a region increases because of frequent forest fires, what most likely happen to the amount of carbon dioxide in the atmosphere? a. it will increase because photosynthesis will speed up. b. it will decrease because dead trees are gone. c. it will increase because more carbon is converted to co₂ gas. d. it will stay the same because carbon just cycles naturally

Explanation:

Combustion of organic - matter in forest fires releases carbon stored in trees as carbon dioxide. Photosynthesis would not speed up due to forest fires, and the presence of dead trees is not the main factor affecting carbon - dioxide levels here. Carbon cycling does not mean the amount stays the same when there is an increase in a major source of carbon - dioxide release.

Answer:

C. It will increase because more carbon is converted to CO₂ gas.
