Explanation:
Detailed explanation-1: -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, can only exist where there is sunlight. Sea predators can easily catch their prey where the water is shallow.
Detailed explanation-2: -Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem. Microflora like algae, and macroflora, such as seaweeds, marsh grasses, and mangrove trees (only in the tropics), can be found here.
