Autotrophic Organisms: The Self-Feeders of the Natural World

Autotrophic organisms are capable of producing their own food using energy from sunlight, water and carbon dioxide. They are also known as self-feeders or producers. These organisms can make their own organic compounds from simple inorganic substances such as carbon dioxide and water, using energy from the sun or chemical reactions.
Examples of autotrophic organisms include plants, algae, and cyanobacteria. These organisms are essential for the survival of most living beings on Earth, as they provide the oxygen and food that other organisms need to survive.
Autotrophic organisms have specialized cells and organs that allow them to capture and convert light energy into chemical energy. For example, plants have chloroplasts, which contain the pigment chlorophyll and are responsible for absorbing light energy and converting it into glucose and oxygen.
In contrast, heterotrophic organisms, such as animals, are unable to produce their own food and must rely on consuming other organisms or organic matter to survive.
