What role does cellular respiration play in the carbon cycle?

a. plants release oxygen.
b. plants absorb carbon dioxide.
c. animals produce carbon dioxide.
d. animals absorb oxygen.

B. plants absorb carbon dioxide.

Cellular respiration: CO2 is sent back into the atmosphere, as both plants and animals use producer sugar to release the stored energy to undergo living functions. So I would conclude the answer is B since they utilize CO2 to build sugar molecules as manufacturers undergoing photosynthesis.

Explanation:

Carbon dioxide is an atmospheric component that has various essential environmental roles. It is a greenhouse gas that traps heat from infrared radiation into the atmosphere. In the weathering of rocks, it plays a key function. It is the plants' carbon source. The organic stuff is stored in sediments, biomass, and carbonate in rocks such as calcareous stone.

In mid-ocean rims, hotspots, and volcanic subduction arches the main source of carbon/CO2 is released from the Earth's interior. The metamorphism of carbonate stones, which convey the crust of the oceans, derives much of the CO2 emitted in subduction zones. Much of the total CO2 emission was deposited in the mantle when the earth originated, especially as mid-ocean ridges and hotpot volcanoes. Some of the emissions of carbon remain as CO2, some are dissolved in the oceans, some are kept in living or dead and degrading organisms as bio-mass and some in carbonate rock. Some are held in the environment. The burial of sedimentary strata, especially coal and black shales, which store organic carbon from untreated biomass and carbonates rocks such as limestone, is removed for long-term storage (calcium carbonate).
