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: –Option B is correct because all animals and fungi are heterotrophs as they can’t produce their own food. They all depend on the autotrophs( primary producers) and on other organisms for food.

Detailed explanation-3: -Autotrophs are the organisms which can prepare their own food. Green plants, cyanobacteria / blue green algae and certain bacteria are autotrophic in nature and prepare their own food. They perform phosynthesis during the day and respiration during both day and night.

Detailed explanation-4: -Heterotrophs cannot synthesize their own food and rely on other organisms(both plants and animals) for nutrition.

Detailed explanation-5: -Two types of autographs namely Photoautotrophs utilize sunlight to produce food and Chemoautotrophs that utilize energy from chemical reactions to produce food. Complete answer: Autotrophs are the organisms that produce their food using inorganic sources.
