8. what kind of compounds do animals release into the ground when they decompose? explain.

a. oxygen compounds
b. aluminum compounds
c. carbon compounds
d. nitrogen compounds

C. Carbon compounds

Explanation:

The animals are living organisms, so they eventually die. As they die, their bodies start to fall apart in a process known as decomposition. This process is caused by the microbes. As the bodies of the animals are decomposing, multiple compounds are released into the soil. One of the those compounds are the carbon compounds. The animals are natural storage of carbon because throughout their lives they consume it through their food, so parts of it are retained into their bodies.
