Question

Identify the process depicted in the diagram given below.

Weathering Rock minerals

• A. Phosphorus cycling in a terrestrial ecosystem
• B. Carbon cycle in the biosphere
• C. Hydrological cycle
• D. Nitrogen cycle

Answer 1

The correct option is

C

Phosphorus cycling in a terrestrial ecosystem

The cycle represented above is the phosphorus cycle. The phosphorus cycle is a sedimentary cycle, it has no gaseous component. The cycle starts from weathering of rocks and the phosphate salt mixes with soil which is then utilized by the producers and stored as organic phosphate. The organic phosphates formed by the producers are transferred to the consumers. And these phosphates return back to the soil from the biotic components when they are broken down by the decomposers. And the cycle begins again.
