Question

the carbon cycle plays a key role in which two processes in the ocean?
□ photosynthesis
□ transpiration
□ respiration
□ evaporation

Explanation:

• Photosynthesis: Marine plants/algae use CO₂ (from carbon cycle) to make food.
• Respiration: Marine organisms release CO₂ (part of carbon cycle) by breaking down food.
• Transpiration (terrestrial plants), evaporation (water cycle) don't involve carbon cycle in ocean.

Answer:

• photosynthesis
• respiration
