Question

Which of the following statements describe sinks for atmospheric CO2? Select all that apply.

Answer 1

Answer:  The following statements describe sinks for atmospheric $CO_{2}$ :

A. Biomass decomposes via anaerobic respiration in the deep soil.

B. Plants on land take up carbon dioxide via photosynthesis.

E. Carbon is transferred from the surface ocean to the deep ocean via the “biological pump” of settling organic matter.

Anaerobic respiration utilizes  $CO_{2}$ to break down biomass. Plants and trees consume atmospheric $CO_{2}$ .  

Biological pump play a critical role in segregation of $CO_{2}$ from atmosphere.

Therefore the correct options in this case are (a),(c) and (e)
