Question

which of the following is a way phosphorus enters the soil ecosystem? photosynthesis, weathering of rocks, evaporation, respiration

Explanation:

Phosphorus enters the soil ecosystem mainly through the weathering of rocks. Weathering breaks down rocks and releases phosphorus - containing minerals into the soil. Photosynthesis is related to the conversion of light energy into chemical energy in plants and has nothing to do with phosphorus entering the soil. Evaporation is a part of the water - cycle process and not related to phosphorus entry into soil. Respiration is a metabolic process in organisms and not a pathway for phosphorus to enter the soil.

Answer:

Weathering of rocks
