A
Weathering
💡 Explanation:
A. Weathering is the breakdown of rocks into smaller particles by the action of various environmental factors like wind, water, sunlight etc.
B. Respiration is the process by which living organisms derive energy by the oxidation of various complex organic substances.
C. Photosynthesis is the process by which green plants capture solar energy and convert it into light energy.
D. Nitrification is the conversion of ammonia into nitrates and is performed in two steps, nitrite formation and nitrate formation.
E. Condensation is the process by which gas changes into liquid drops.
Since rocks are made up of phosphorus and contain phosphates, their weathering will cause dissolution of phosphates in the soil and thus, phosphorus enters the ecosystem.
So, the correct answer is 'Weathering'.
