Question

2 multiple choice 1 point nutrients circulate endlessly throughout the environment in complex cycles called
○ photosynthe cycles
○ eutrophication cycles
○ biogeochemical cycles
○ respiration cycles
previous

Explanation:

• Photosynthesis cycles: Photosynthesis is a process by which plants make food, not a cycle for nutrient circulation in the environment.
• Eutrophication cycles: Eutrophication is the enrichment of water with nutrients (often leading to algal blooms), not the general term for nutrient cycles in the environment.
• Biogeochemical cycles: These are cycles that involve the biological, geological, and chemical aspects of the environment, and they describe how nutrients (like carbon, nitrogen, phosphorus) circulate through the environment (including living organisms, soil, water, air).
• Respiration cycles: Respiration is a process of energy release in organisms, not a cycle for nutrient circulation in the environment.

Answer:

C. biogeochemical cycles
