How living things get food पोषण के प्रकार
| Mode | How | Examples |
|---|---|---|
| Autotrophic स्वपोषी | Make their own food by photosynthesis | Green plants, algae |
| Heterotrophic विषमपोषी | Take food from other organisms | Animals, fungi, most bacteria |
| — Holozoic प्राणिसम | Take in food and digest it inside | Humans, cow, lion, amoeba |
| — Parasitic परजीवी | Live on or in a host and take food from it | Cuscuta (amarbel), tapeworm, lice, leech |
| — Saprotrophic मृतजीवी | Feed on dead, decaying matter | Mushroom, bread mould, yeast |
Special cases: the pitcher plant is green and makes its own food, but also traps insects for nitrogen. A lichen is an alga and a fungus living together (symbiosis); Rhizobium bacteria live in the roots of pulses and fix nitrogen. Also see photosynthesis and life processes.
Goes with NCERT Science Class 7 and Class 10 (Life processes).
