Question

6 multiple choice 1 point the phosphorus in all biological tissues can be traced back to atmospheric phosphorus gas phosphorus dissolved in the ocean and taken up by shellfish volcanic activities phosphorus in animal bones phosphorus weathered from rock clear my selection

Explanation:

The phosphorus cycle starts with phosphorus weathered from rocks. This phosphorus enters soil and water, is taken up by plants, then moves through the food chain to biological tissues. Atmospheric phosphorus gas is negligible, shellfish take up dissolved phosphorus (but the source of that dissolved phosphorus is from rock weathering), volcanic activities contribute little, and animal bones are part of the cycle after plants/animals take up phosphorus from the environment (originating from rock weathering).

Answer:

E. phosphorus weathered from rock
