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: -Some examples of autotrophs include plants, algae, and even some bacteria.

Detailed explanation-3: -Autotrophs are also referred to as producers because they make their food. From the list, Chara, Nostoc, Porphyra, Wolfia, Nitrosomonas, and Nitrobacter are autotrophs.

Detailed explanation-4: -Animals are heterotrophs. They do not possess chlorophyll pigment to undergo photosynthesis, hence they feed on living organisms.

Detailed explanation-5: -Autotrophs and heterotrophs are the two classifications of organisms on the basis of nutrition. Autotrophs are organisms that can prepare their own food. On the contrary, heterotrophs depend on autotrophs and other organisms for nutrition.
