Detailed explanation-1: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

Detailed explanation-2: -Examples of autotrophs include plants, algae, plankton and bacteria. The food chain is comprised of producers, primary consumers, secondary consumers and tertiary consumers.

Detailed explanation-3: -Plants prepare there own food, so they are called autotrophs. Autotrophs are any organisms that are capable of producing their own food. This is achieved by using light energy, water and carbon dioxide.

Detailed explanation-4: -Plants are called autotrophs because they use the energy of sunlight to store energy in food (glucose and starch). They are not dependent on other organisms for energy and instead directly obtain it from sunlight.
