Solution
| Autotrophic nutrition | Heterotrophic nutrition |
| 1. It is the mode of nutrition in which organisms produce their own organic food. | It is the mode of nutrition in which organisms depend on other organisms for their food. |
| 2. Organisms producing their own food are known as autotrophs. | Organisms depending on others for food are known as heterotrophs. |
| 3. Autotrophs use simple inorganic substances present in the surroundings to produce food. | Heterotrophs depend on other organisms to get their food. |
| E.g. Plants | E.g. Fungi |
