Question

if a disruption occurs in the carbon cycle within an ecosystem, which of the following is a likely consequence?
a. imbalance in nutrient cycling
b. accelerated growth of primary producers
c. increased biodiversity
d. enhanced ecosystem stability

Explanation:

The carbon cycle is a part of nutrient cycling. A disruption in the carbon cycle would thus lead to an imbalance in nutrient cycling. Primary producers' growth depends on balanced cycles (not just carbon). Biodiversity and ecosystem stability are likely to decrease (not increase or enhance) with a carbon - cycle disruption as it can lead to habitat degradation, species loss etc.

Answer:

A. Imbalance in nutrient cycling
