Every habitat has two kinds of components:
- Biotic — living: plants, animals, fungi, bacteria, even the microbes in soil.
- Abiotic — non-living: sunlight, air, water, soil, temperature, pressure, minerals.
They constantly interact. Plants need sunlight (abiotic) to grow; animals eat plants (biotic link).
Example
In a pond: fish, algae, frogs (biotic) + water, sunlight, oxygen dissolved in water (abiotic). Drain the water → everything dies — shows how tightly linked they are.
💡 Tip:Damage one abiotic factor (pollution, heat) and many biotic species suffer.
