Current Question (ID: 11302)

Question:

Which of the following statements does not justify the importance of photosynthesis?

Options:

1. it is the primary source of all food on earth.
2. it is responsible for the release of oxygen into the atmosphere.
3. it is responsible for the water balance on earth.
4. use of energy from sunlight by plants doing photosynthesis is the basis of life on earth.

Solution:

Photosynthesis is an essential process that plays a crucial role in the survival of life on Earth. It is the primary source of all food on earth and provides the energy that fuels most of the world's ecosystems. Photosynthesis is also responsible for the release of oxygen into the atmosphere, which is necessary for the survival of aerobic organisms. The use of energy from sunlight by plants to carry out photosynthesis is the basis of life on earth, as it provides the foundation for most food chains and ecosystems. However, photosynthesis is not directly responsible for the water balance on earth. The water cycle, which involves processes like evaporation, condensation, and precipitation, is responsible for the movement and distribution of water on the planet.
