AUTOTROPHIC MODE OF NUTRITION: It is the mode of nutrition in which plant prepare their own food by simple inorganic substance......AUTOTROPH: Those organisms who follow Autotrophic mode of nutrition is called Autrophs.......HETEROTROHS: Those organisms who follow Heterotrophic mode of nutrition is called Heterotrophs..

Autotrophic, Autotrophs, and Heterotrophs
Autotrophic organisms are those that can produce their own food using inorganic substances through processes like photosynthesis or chemosynthesis. They are self-sustaining and do not rely on other organisms for their energy needs. On the other hand, heterotrophic organisms cannot produce their own food and must consume organic matter to obtain energy.

Autotrophs
- Autotrophs are organisms that are capable of synthesizing their own food using external sources of energy.
- They are the primary producers in a food chain, as they convert energy from the sun or inorganic compounds into organic molecules.
- Examples of autotrophs include plants, algae, and some bacteria.

Heterotrophs
- Heterotrophs are organisms that cannot produce their own food and must consume other organisms or organic matter to obtain energy.
- They are dependent on autotrophs for their energy needs and play a crucial role in energy transfer within ecosystems.
- Examples of heterotrophs include animals, fungi, and most bacteria.
In summary, autotrophs are self-sustaining organisms that can produce their own food, while heterotrophs rely on other organisms for their energy needs. Both types of organisms are essential for maintaining the balance of energy flow within ecosystems.
