Question

imagine a forest where the amount of photosynthesis and cellular respiration are equal over one year. what will happen to the total amount of carbon dioxide in the atmosphere? a. it will decrease, because carbon is locked in biomass. b. it will increase, because organisms keep breathing out co₂. c. it will stay roughly the same, because inputs and outputs are balanced. d. it will go to zero, because photosynthesis removes co₂.

Explanation:

Photosynthesis takes in carbon - dioxide and cellular respiration releases it. When their amounts are equal in a forest over a year, the inputs and outputs of carbon - dioxide are balanced, so the total amount in the atmosphere stays roughly the same.

Answer:

C. It will stay roughly the same, because inputs and outputs are balanced
