Answer:
AUTOTROPHIC NUTRITION
- Usually members of the plant kingdom and certain unicellular organisms like cyanobacteria
- Autotrophs are producers which prepare their own food.
- These can be classified as photoautotrophs and chemoautotrophs
- The chloroplast helps in preparing food.
- They obtain energy from inorganic sources by converting light energy into chemical energy
- 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.
- Green plants, algae and a few photosynthetic bacteria are examples of autotrophs.
HETRATROPHIC NUTRITION
- 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.
- Can move from one place to another in search of food and shelter.
- Cows, buffaloes, tigers, horses, humans are examples of heterotrophs.
