What term describes organisms that produce their own food?

The correct term for organisms that produce their own food is "autotrophic." Autotrophs are capable of synthesizing organic compounds from inorganic sources through processes such as photosynthesis or chemosynthesis. This ability allows them to convert energy from sunlight or chemical reactions into forms that can be stored and used as food.

For instance, plants, algae, and some bacteria are considered autotrophs because they can convert light energy into chemical energy. In photosynthesis, for example, autotrophic organisms use carbon dioxide and water, utilizing sunlight, to create glucose and oxygen, thus feeding themselves while contributing oxygen to the environment.

The other terms do not accurately describe organisms that produce their own food. Heterotrophic refers to organisms that cannot produce their own food and rely on consuming other organisms for nourishment. Pathogenic pertains to organisms that can cause disease, and mesophilic is a term used to describe organisms that thrive at moderate temperatures, which is not directly related to their capability to produce food.
