In biology, plants are the most popular examples of producers. Other examples include algae, seaweed, phytoplankton and some bacteria are also producers. Good examples include cyanobacteria and green and purple sulfur bacteria.
Producers are organisms that are capable of producing their own food using water, light and other chemicals. They are also known as autotrophs. Most autotrophs achieve this via either photosynthesis, where light is used to synthesize energy, or chemosynthesis, where chemical are used to synthesize energy. Producers play an important role in the ecosystem. They serve as the primary food source for consumers (also known as heterotrophs).
