What do you think would happen to the rates of photosynthesis of seagrass and algae if their habitat became muddied when channel clearing caused sediment to stay mixed in with the water? Explain.

Less light reaching the plants means less photosynthesis.
1) the plants on the floor wouldn't get as much light, since the tree branches above them "hog" the light and cover the floor in shade. The floor leaves get less light, the canopy get more.

2) Sea grass in muddied water will have the same problem as 1). Their light supply is blocked by the mud, and so light doesn't reach them, so they can't photosynthesis
