There are two process by which organisms obtain nutrition . One is the autotrophic nutrition and the other is heterotrophic nutrition .
| Autotrophic Nutrition | Heterotrophic Nutrition |
|---|---|
| In autotrophic nutrition organism prepares its food from simple substances present in the surroundings . | In heterotrophic nutrition organism obtains food from digesting organic compounds . |
| Autotrophs are the producers in the food chain . | Heterotrophs are the consumers in the food chain . |
| Example : Plants obtain food by autotrophic nutrition . | Example : Some plants and all animals obtain food by heterotrophic nutrition . |
| utotrophs are fundamental to the food chains of all ecosystems in the world. They take energy from the environment in the form of sunlight or inorganic chemicals and use it to create energy-rich molecules such as carbohydrates. This mechanism is called primary production. | Other organisms, called heterotrophs, take in autotrophs as food to carry out functions necessary for their life. Thus, heterotrophs — all animals, almost all fungi, as well as most bacteria and protozoa — depend on autotrophs, or primary producers, for the energy and raw materials they need. |
