Key Differences Between Heterotrophs and Autotrophs
Given below are the substantial difference between heterotrophs and autotrophs, on the basis of their mode of nutrition, their dependency, their process of obtaining food, etc.
- Animals like cow, dog, elephant, rhino, lion, etc. are said to be as heterotrophic, as these animals depends directly on indirectly on others for their food; whereas green plants, algae and few bacteria are said to be autotrophic as they are able to prepare their own food by the process of photosynthesis which needs sunlight, air, water, and sunlight.
- Heterotrophs are considered as consumers and are placed at a secondary or tertiary level in the food web, while autotrophs are primary producers.
- Heterotrophs do not contain chloroplast, chlorophyll and hence are unable to prepare their own food, also depend on other for obtaining energy. Autotrophs contain chloroplast, chlorophyll and hence are able to produce their own food and depends on sunlight, air, and water for the preparation of food.
- Heterotrophs are able to move from one place to another in search of food, autotrophs are not able to move.
- Heterotrophs obtain their energy directly or indirectly from other organisms, while autotrophs obtain energy from inorganic sources, where they convert light energy (sunlight) into chemical energy.
- Heterotrophs depend on autotrophs for their food, while autotrophs are not.
