Question

The carbon that animals release into the air comes from

A. nitrogen fixation
B. cellular respiration
C. perspiration
D. transpiration

Answer 1

B cellular respiration

Step-by-step explanation:

animals breathe in oxygen and breathe out carbon dioxide as a waste product or should I say by product. Now oxygen goes into the cell and releases carbon after producing energy to the body, the carbon mix with oxygen and become co2 which is released into the atmosphere.

Answer 2

Possibly B. cellular respiration

Step-by-step explanation:

Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere.
