Question

How does phosphorus cycle through the biosphere?

Answer 1

Phosphorus cycles through the biosphere through the phosphorous cycle.

Explanation:

Phosphorus cycles through the biosphere through what is known as the phosphorus cycle.

In regards to the biosphere specifically, phosphorus moves through all living organisms, including humans. Phosphates make up DNA, ATP, and RNA. Plants and fungi take in phosphates through their roots. Herbivores consume these plants and omnivores and carnivores then consume the herbivores. When an organism dies, decomposers return phosphorus to the soil.
