Question

Biogeochemical cycles can be traced in

• A. Ecosystems
• B. Biomes
• C. Only water
• D. Both A and B

Answer 1

The correct option is D Both A and B

The inorganic nutrients cycle though more than the organisms, however, they also enter into the atmosphere, the oceans and even rocks. Since these chemicals cycle through both the biological and the geological world, we call the overall cycles biogeochemical cycles.

Each chemical has its own unique cycle, but all of the cycles do have some things in common. Reservoirs are those parts of the cycle where the chemical is held in large quantities for long periods of time. In exchange pools, on the other hand, the chemical is held for only a short period of time. The length of time a chemical is held in an exchange pool or a reservoir is termed its residence time.
