Statement 2 is correct because India's forest cover remains well below the National Forest Policy target of 33%. Statement 3 is incorrect because tropical forests in India are highly diverse rather than homogeneous, and Statement 4 is incorrect as the actual productivity is much lower than 3.5 cubic meters per hectare.

2. Circulation of matter in the biosphere ecosystem is unidirectional.
Select the correct answer using the codes given below.

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2
Reveal answer Fill a bubble to check yourself
D Correct answer

Consider the following statements about availability of oxygen on Earth
1. Most oxygen of Earth's biosphere is stored in the lithosphere.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The lithosphere contains the largest reservoir of Earth's oxygen (about 99.5%), primarily bound in silicate and oxide minerals. Phytoplankton in the oceans are responsible for producing a major portion of the atmospheric oxygen through photosynthesis. Additionally, photolysis (the breakdown of water vapor by solar radiation in the upper atmosphere) also releases free oxygen.
