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

Detailed explanation-3: -Heterotrophic bacteria derive energy from organic compounds. They help in nutrient recycling. They decompose dead and decaying plants and animal remnants and help in biodegradation. Heterotrophic bacteria are used for making curd, antibiotics, nitrogen-fixation, etc.

Detailed explanation-4: -Some types of bacteria are autotrophs. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar.
