NEET BIOLOGY

Detailed explanation-1: -Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms.

Detailed explanation-2: -Because autotrophs do not consume other organisms, they are the first trophic level. Autotrophs are eaten by herbivores, organisms that consume plants.

Detailed explanation-3: -Autotrophs rely on either light or chemical energy to turn CO2 into organic carbon molecules. Photoautotrophs are photosynthesizing organisms such as algae and higher plants that use light for this process. Heterotrophs, in contrast, obtain their chemical energy from preexisting organic molecules.

Detailed explanation-4: -Without autotrophs, heterotrophs cannot survive. So autotrophs aren’t only producers because they make food for themselves, but also because they make the energy that all other living things depend on.

Detailed explanation-5: -True 14. Autotrophs do not need to eat food because they make food. the sun 15. The energy in food originally came from ATP.
