Question

which process plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus? photosynthesis transpiration decomposition respiration

Explanation:

• Photosynthesis: Mainly involves carbon (converting CO₂ to glucose) but less central to nitrogen and phosphorus cycles.
• Transpiration: Is about water movement in plants, not directly related to these nutrient cycles.
• Decomposition: Decomposers break down organic matter, releasing carbon, nitrogen, and phosphorus back into the environment, crucial for their biogeochemical cycles.
• Respiration: Releases carbon (as CO₂) but has a more limited role in nitrogen and phosphorus cycling compared to decomposition.

Answer:

C. decomposition
