Question

how is atmospheric deposition part of the phosphorus cycle? 5 points rainfall organic dust lightning sunlight

Explanation:

Atmospheric deposition in the phosphorus cycle mainly occurs through rainfall. Rainfall can dissolve phosphorus - containing compounds in the atmosphere and deposit them on the Earth's surface, making phosphorus available for plants and other organisms in the ecosystem. Organic dust is more related to carbon and nutrient cycling in a different context (e.g., decomposition and soil organic matter). Lightning is significant in the nitrogen cycle (fixing nitrogen), and sunlight is for photosynthesis (not directly for phosphorus deposition).

Answer:

Rainfall
