DENDROLOGY

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: -Plants like blue-green algae and bacteria such as cyanobacteria are considered to be examples of autotrophs.

Detailed explanation-3: -Autotrophic nutrition is the type of nutrition where organisms synthesize their own food. They are called producers in the ecosystem. They use sunlight, water, and carbon dioxide to synthesize food. Autotrophic nutrition is of two types such as photoautotrophs and chemoautotrophs.

Detailed explanation-4: -No, all plants are not autotrophic. Some of the non-green plants such as dodder plants obtain their food from other plants and these plants are heterotrophic plants. Heterophic plants generally do not possess chlorophyll, which inhibits their ability to prepare their own food.
