Which of the following most often controls the rate of nutrient cycling in ecosystems? a. rate of decomposition of detritusb. primary productivityc. secondary productivityd. both b and c

The correct option is A.

Explanation:

Nutrient cycling refers to the process of movement and exchange of various organic and inorganic materials through the biotic and abiotic components of the biosphere. Nutrient cycling is a very important process that ensures that the ecosystem is balanced. The principal factor that controls the rate of nutrient cycling in ecosystem is detritus. Detritus refers to decomposed organic matters. Therefore, the rate of decomposition of organic and inorganic nutrients majorly determine the rate at which nutrient cycling occurs.
