Question

1. the carbon cycle includes two main categories of processes. some that release carbon into the atmosphere and some that act as carbon reservoirs. the diagram below shows both major process categories, and gives examples of activities for both. which of these disruptions would cause a decrease in atmospheric carbon? carbon output to atmosphere - organism respiration - fuel combustion - cement production atmospheric carbon carbon reservoirs - soils and detritus - dissolved organic carbon - ocean sediments - terrestrial biota - marine biota - buried fossil fuels - rocks a reduction in the consumption of fossil fuels a decreases in populations marine biota the destruction of terrestrial biota an increase in cement production

Explanation:

Fossil - fuel consumption releases carbon into the atmosphere. Reducing it would decrease carbon output to the atmosphere. A decrease in marine biota would not necessarily reduce atmospheric carbon as they are carbon reservoirs. Destruction of terrestrial biota reduces carbon - sequestering ability. An increase in cement production releases more carbon.

Answer:

A. A reduction in the consumption of fossil fuels
