Question

Statement 1: Light is the primary source of energy on earth.

Statement 2: The energy required for the sustenance of life on earth is obtained by photosynthesis

• A. Absorption of light by Chlorophyll → Splitting of water to H₂ and O₂ → Reduction of CO₂ → Carbohydrate formation
• B. Splitting of water to H₂ and O₂ → Reduction of CO₂ → Absorption of light by Chlorophyll → Carbohydrate formation
• C. Splitting of water to H₂ and O₂ → Absorption of light by Chlorophyll → Reduction of CO₂ → Carbohydrate formation
• D. Absorption of light by Chlorophyll → Reduction of CO₂ → Splitting of water to H₂ and O₂ → Carbohydrate formation

Answer 1

The correct option is B

Splitting of water to H₂ and O₂ → Reduction of CO₂ → Absorption of light by Chlorophyll → Carbohydrate formation

Sun is the ultimate Power Source. Every morning the sun rises, bringing light and heat to the earth, and every evening it sets. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Hence sunlight is the primary source of energy on earth That helps in carrying out the processes of photosynthesis and sustenance of life on earth.
