Question

use your understanding of the phosphorus cycle to answer the questions provided. phosphorus cycles between living things and the. done

Explanation:

In the phosphorus cycle, phosphorus moves between living organisms (biotic components) and the non - living components of the environment. The non - living components here include the soil, water (in aquatic ecosystems), and rocks (as phosphorus is often found in mineral form in rocks). So the main non - living reservoir for phosphorus in its cycle with living things is the environment (specifically the geosphere, hydrosphere, and lithosphere components like soil, water, and rocks).

Answer:

environment (or soil/rocks/water, as part of the non - living environment)
