- Autotrophs can store light energy and chemical energy.
- They are placed at the primary level in the food chain.
- They cannot move from their place.
- Examples:- Green plants, algae and a few photosynthetic bacteria are examples of autotrophs.
Heterotroph:-
- All members of the animal kingdom
- Heterotrophs are the consumers who depend on other sources for their food.
- These can be classified as photoheterotrophs and chemoheterotrophs
- They do not contain chloroplast, so cannot prepare food.
- They obtain energy directly or indirectly from other organisms.
- Heterotrophs cannot store energy.
- These are placed in the secondary or tertiary level in the food chain.
