What is a producer in biology?

In biology, producers are organisms that produce organic compounds for the entire ecosystem. These organisms are at the beginning of the food chain; they can produce nutrients and compounds that other organisms can utilize.

Plants are often classified as producers, since plants have the ability to undergo photosynthesis. Plants obtain light energy from the sun, which catalyzes the chemical reaction of photosynthesis. The final product of photosynthesis is oxygen for the atmosphere and glucose for the plant. Producers that are plants are also full of nutrients themselves, which makes them great food sources for the other organisms within the ecosystem.
