It enters the ocean from sources like hydrothermal vents. organism that can produce its own food and nutrients from chemicals in the atmosphere, usually through photosynthesis or chemosynthesis. This is due to their slow rate of reproduction. The marine ecosystem is made up of a complicated series interconnected energy producers—like plants and photoplankton—and consumers—from plant-eaters to meat-eaters, both great and small. Phytoplankton form the basis of life in the ocean. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. It is also called the marine food web by marine scientists.
