Detailed explanation-1: -The heterotrophs consume the autotrophs or the sugar molecules. The heterotrophs perform cellular respiration to break down these complex organic molecules and release energy in the form of ATP. Thus, indirectly or directly, all autotrophs and heterotrophs-depend on the sun as the source of energy.

Detailed explanation-2: -Heterotrophs depend either directly or indirectly on autotrophs for nutrients and food energy. For example, raccoons might consume corn (maize) planted in a field, or they might catch and eat rodents that rely on corn as a food source.

Detailed explanation-3: -Heterotrophs still depend on the sun for energy because they get energy indirectly. Getting energy indirectly means that you get energy from another organism that does not produce the energy. Say a heterotroph, such as a zebra, eats grass, which gets energy from the sun.

Detailed explanation-4: -Heterotrophs are organisms that obtain energy from other living things. Like sea angels, they take in organic molecules by consuming other organisms, so they are commonly called consumers. Heterotrophs include all animals and fungi as well as many protists and bacteria.

Detailed explanation-5: -All heterotrophs must eat food to get energy. True 14. Autotrophs do not need to eat food because they make food.
