Question

Explain the process by which autotrophs make their

food and also write its biochemical reaction.​

Answer 1

Autotrophs make their own food by the process of photosynthesis. The process by which plants make their own food using raw materials like sunlight, chlorophyll, water and carbon dioxide is called photosynthesis. The two inorganic substances used by autotrophs to make food are carbon dioxide and water.

(iv) Green plant: (d) Saprophytic nutrition

(ii) Amoeba: (b) Autotrophic nutrition

Answer 2

Autotrophs make their food by the use of mechanism Photosynthesis.

• Photosynthesis represents the fundamental mechanism by which autotrophs, in the active presence of chlorophyll and direct sunlight, typically take in water from the fertile soil, carbon dioxide from the air and then turn it into carbohydrate.

• The biochemical reaction involved in the process is -

• 6CO2 ( Carbon Di Oxid) + 6H2O ( Water) →→ C6H12O6 (Glucose) + 6O2 (Oxygen)
