Respuesta :
Brightness decreases with depth is the correct statement which explains the variation in ocean waters with varying capacity for phytoplankton and other organisms to perform photosynthesis. The correct option to this question is B.
- Photosynthesis, which takes place in sunshine, is the first step in almost all food chains. As a result, marine plants will only grow close to the surface where there is access to light.
- Of course, this will keep herbivores and their predators at the surface as well.
- Because sunlight can only permeate the water environment to a depth of 50 to 100 m in oceanic water bodies, phytoplankton are only found there.
- Photosynthesis depends on sunshine. Mineral nutrients are also important for growth, with land providing the most.
