How do organisms respond when their ecosystem is disrupted?

Most of the organisms in the ocean exists in the shallow water over the continental shelves. Why is this true?
Producers, the beginning of all food chains, live best where there is sunlight.
Sea predators can easily catch their prey where the water is shallow.
