D) Can only occur when wind action is nil

Question

Quizplus · Accepted Answer

Benthic-planktonic coupling refers to the interaction between the benthic (bottom-dwelling) and planktonic (floating) organisms in aquatic environments. This interaction is not limited to any specific depth (deep or shallow) or specific conditions such as the presence of a thermocline or wind action. Instead, it can be influenced by various factors, including the mixing of water columns. The development of an isothermal water column, where the temperature is uniform with depth, can enhance the mixing of nutrients and organic matter between the surface and the bottom, facilitating benthic-planktonic coupling. This process is not restricted to the absence of wind or the permanence of a thermocline.
