They control the population by feeding on the primary consumers, ensuring that they cannot exceed the number that the ecosystem can withstand. An important primary consumer is a zoo plankton. These organisms are called producers, and they form the base of any food chain, as organisms that use sunlight or chemical energy to create their own food. Some examples of quaternary consumers are hawks and white sharks, which also are carnivores.
