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.

Detailed explanation-2: -Producers are autotrophs or organisms that utilize the sunlight and chlorophyll within the plant to produce energy for the plant to grow. Heterotrophs are those organisms on the food pyramid that eat producers.

Detailed explanation-3: -Autotrophs are vital to all ecosystems because all organisms need organic molecules and only autotrophs can produce them from inorganic compounds. There are two basic types of autotrophs: photoautotrophs and chemoautotrophs.
