The green plants in a terrestrial eco-system absorbs sunlight that falls on their leaves and convert it into food energy. The percentage of solar radiation absorbed by all green plants for the process of photosynthesis is about 

The correct answer is 1%.

Key Points

• Green plants capture about 1% of the energy of sunlight falling on their leaves for the process of photosynthesis.
• This energy is converted into chemical energy in the form of food. At subsequent levels only 10% of the energy is available.

Additional Information

• Photosynthesis is the process by which green plants produce carbohydrates and release chemical energy by absorbing carbon dioxide, water, and sunlight in the presence of chloroplasts.
  • Sunlight is the main source of energy for photosynthesis.
  • The gas that plants absorb during photosynthesis is Carbon dioxide.
  • The gas that plants release during photosynthesis is Oxygen.
  • The gas that plants absorb during respiration is Oxygen.
  • The gas that plants release during respiration is Carbon dioxide.
  • The rate of photosynthesis is maximum - Red light.
  • Rate of photosynthesis is minimum – Yellow light.
  • The pigment in chloroplasts that gives plants their green color is Chlorophyll.
  • The only metal present in chlorophyll is Magnesium.
