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.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
