Question

according to the law of conservation of matter, matter is not created or destroyed, it only changes form. once carbon becomes part of the biotic components of the carbon cycle, how does it re-enter the atmosphere? all but one could apply. a respiration b ocean uptake c factory emissions d combustion of fossil fuels

Explanation:

The question is about the carbon cycle and how carbon re - enters the atmosphere. Respiration (A) releases CO₂ from living organisms. Combustion of fossil fuels (D) and factory emissions (C) also release carbon - based gases into the atmosphere. Ocean uptake (B) is a process where the ocean takes in carbon from the atmosphere, not a way to release it back. So the one that does not apply to re - entering carbon into the atmosphere is ocean uptake.

Answer:

B. ocean uptake
