Autotroph

An organism that uses organic carbon for its carbon needs and sunlight for its energy needs would be called an autotroph.

<h3>What are autotrophs?</h3>

An organism that has the ability to make its own food from inorganic materials is known as an autotroph. Contrarily, heterotrophs are organisms that are dependent on the eating of other species for their survival because they are unable to manufacture their own nutrients. Because they frequently provide food for heterotrophs, autotrophs are crucial producers in the ecosystem.

The most prevalent kinds of autotrophs are plants, which make their own food through the process of photosynthesis. In order to create nutrition from light, plants contain a specialized organelle called a chloroplast within their cells. These organelles generate glucose, a basic sugar needed for energy, as well as oxygen as a byproduct when combined with water and carbon dioxide. In addition to providing nutrients for the producing plant, glucose also serves as an energy source for the plants' consumers. Algae, plankton, and some varieties of bacteria are additional examples of autotrophs that engage in photosynthesis.
