Autotrophs and Heterotrophs:

Autotrophs are organisms that can produce their own food through the process of photosynthesis. They are also called producers. Heterotrophs, on the other hand, cannot produce their own food and depend on other organisms for their food. They are also called consumers.

Autotrophic Nutrition:

Autotrophic nutrition is the process by which autotrophs produce their own food through the process of photosynthesis. In this process, autotrophs use sunlight, carbon dioxide, and water to produce glucose and oxygen. The glucose is used by the autotrophs as a source of energy, while the oxygen is released into the atmosphere.

Heterotrophic Nutrition:

Heterotrophic nutrition is the process by which heterotrophs obtain their food from other organisms. Heterotrophs can be classified into different types based on the type of food they consume. These include:

- Herbivores: Herbivores consume only plants.
- Carnivores: Carnivores consume other animals.
- Omnivores: Omnivores consume both plants and animals.
- Detritivores: Detritivores consume dead organic matter.
- Parasites: Parasites obtain their food from other organisms while harming them.

Conclusion:

Autotrophs and Heterotrophs are two types of organisms based on their ability to produce their own food. Autotrophs can produce their own food through the process of photosynthesis, while heterotrophs depend on other organisms for their food. Autotrophic nutrition and heterotrophic nutrition are the processes by which autotrophs and heterotrophs obtain their food, respectively.

The organisms which make their own food by simple substances are called Autotrophs. The organisms which depend on other organisms for their food are called Heterotrophs.
