Metabolism is the breaking down of complex substances into simpler molecules. (cell respiration) A True
B) False

Option C

Explanation:

Metabolism can be defined as the combination of catabolism and anabolism.The combination of simpler compounds to form complex compounds is known as anabolism.

The breaking of complex compounds into simpler compounds is known as catabolism.

The metabolism is not a local effect but is a global effect. It helps in maintaining equilibrium inside the body. It can be in terms of temperature, pH and et cetera.

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.

the fossil record provides evidence of a common ancestor to many species.
