Question

Describe the different abiotic components of the environment, with their effect on the biotic components.

Answer 1

The word 'abiotic' means 'non-living'. Light, air, water, soil and temperature are some of the examples of abiotic components of environment.

1. Light: Plants use light to prepare their food.
2. Temperature: Temperature is a measure of how hot or cold something is. Temperature affects the distribution of plants and animals around the planet.
3. Air: Oxygen and carbon dioxide present in air are very important for the survival of organisms. Both plants and animals need oxygen for respiration.
4. Water: Water is very important for living organisms. Water is essential for carrying out photosynthesis in plants. Blood, which transports substances within the human body, is largely composed of water.
5. Soil: Soil is the uppermost layer of the Earth's crust. Soil is very rich in minerals like magnesium, potassium and phosphorus and helps the plant in its growth and development.
