E) is inversely related to rate of respiration.

Question

Quizplus · Accepted Answer

The photic zone is the area in the ocean where sunlight can penetrate and support photosynthesis. In this zone, the rate of photosynthesis by primary producers (such as phytoplankton) exceeds the rate of respiration, leading to a net uptake of CO₂ and release of oxygen. This process is a crucial part of carbon cycling in the ocean. Therefore, option B is the correct answer.

In the Marine Photic Zone, the Rate of Photosynthesis
