Question

Quizplus · Accepted Answer

Phosphorus typically enters ecosystems through the process of rock weathering, as it is released from rocks and minerals into the soil and water.

Answer: D
 Another way phosphorus can enter ecosystems is through geological uplifting, where phosphorus-containing rocks are uplifted from underground and exposed to weathering processes.

Answer: E
 Some phosphorus can also enter ecosystems through atmospheric dust, but this is generally a minor source compared to rock weathering and geological uplifting. Phosphorus is not directly involved in cellular respiration or photosynthesis, although it is an important element for both processes once it enters the ecosystem.
