Question

Which of the following statements explains how carbon enters the soil during the carbon cycle? A. /Carbon enters the soil when decomposers produce it. /B.Carbon enters the soil when organisms die and become fossilized /C. Carbon enters the soil when humans perform respiration and exhale it. /D. Carbon enters the soil when plants make glucose and deposit it into the soil.
whats the answer A/B/C OR /D

Answer 1

The correct option is A.
Both plants and animals have the carbon element in their body. When plants and animals die, their body organs become decay as the result of the activities of the decomposers. The activities of the decomposers releases the carbon in these dead organisms back into the soil.

Answer 2

A. /Carbon enters the soil when decomposers produce it.

 

Carbon is deposited into the soil through decomposers which digests and generate carbon when organisms die and become buried beneath the soil. This process also is observed during the carbon cycle. Carbon cycle is a biogeochemical cycle where the transfer of carbon from the different spheres of the earth occurs. This involves the geosphere, hydrosphere, atmosphere, pedosphere and most especially, the biosphere.
