In the first segment that covers the top part of the ocean the whale sharks producers serve as the basis of the food chain. In the top layer of the ocean enough sunlight hits the water which makes it a good place for planktons to grow. These planktons are then eaten by the whale sharks.
Oceanography applies chemistry, geology, meteorology, biology, and other branches of science to the study of the ocean. It is especially important today as climate change, pollution, and other factors are threatening the ocean and its marine life.
