Question

The reservoir for the gaseous type of biogeochemical cycle exists in the ______.

Options

• stratosphere

• ionosphere

• lithosphere

• atmosphere

Answer 1

The reservoir for the gaseous type of biogeochemical cycle exists in the atmosphere.

Explanation:

These cycles involve gases that continuously circulate through living organisms and the environment, with the atmosphere serving as the primary reservoir for these gaseous nutrients. This distinguishes them from sedimentary cycles whose reservoirs are in the lithosphere. Hence, the atmosphere is the key reservoir for gaseous biogeochemical cycles.
