A large area of forest was destroyed completely by forest fire. Which of the following statements hold(s) true regarding it?

(i) More soil will be eroded as the soil is not protected by trees from wind and rain.
(ii) The land will have more fresh air as there are lesser trees to take in oxygen.
(iii) Wildlife will inhabit the cleared area because more space is available now.
(iv) New trees will grow quickly to replace the burnt ones as the ash of the burnt trees will make the soil more fertile.

A (i) only
B (i) and (iv) only
C (i), (ii) and (iv) only

Actually, forest fires lower the level of nitrogen in the soil. Since nitrogen quantities in the soil is extremely important for plant growth, lowered level of nitrogen is a big barrier in plant growth

Ans 25:

Class : Class 7
THe AntwerpThe answer is (A) because if forest fire occurs there will not be any trees and soil erosion can happen and All the ashes including soil may erode and then how can it make the soil fertile

Ans 26:

Class : Class 6

Ans 27:

Ans 28:

Class : Class 6
a is correct because there willbe soil erosion without trees

Ans 29:
