Which of these disruptions would cause an excess output in the Carbon Cycle?

Complete Question:

The carbon cycle includes processes that release carbon into the atmosphere and places that act as carbon reservoirs. The diagram below shows both major processes that release carbon and major carbon reservoirs. (See attached picture for the diagram being referred to)

Which of these disruptions would cause an excess output in the carbon cycle?

 A. The destruction of terrestrial biota

 B. Increases in marine biota

 C. A reduction in the use of fossil fuels

 D. A thickening of ocean sediments

A. The destruction of terrestrial biota

Explanation:

Terrestrial biota play a very cogent and fundamental role in the regulation of carbon in the carbon cycle. Serving as a reservoir of carbon, terrestrial biota helps in absorbing carbon dioxide from the atmosphere.

Therefore, the destruction of terrestrial biota would lead to an excess output of carbon in the carbon cycle due to the reduction in the capacity of forest and other plant community to absorb carbon dioxide from the environment.

Destruction of terrestrial biota would result in an excess output in carbon when compared to other disruptions.
