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
D (i), (ii), (iii) and (iv)
the answer should be option B not A because ash does act like a natural fertiliser ,. I have already searched on the internet .

I think B is correct option as ash acts as a fertilizer for plants (even if in small quantities). Master Answer (Admin, Revisewise) EXPLAIN the answer to all of us.

i think the answer should be B because the statement 'New trees will grow quickly to replace the burnt ones as the ash of the burnt trees will make the soil more fertile' is also true

yes B is the answer as the ash contains minerals from the other trees.. i agree that the process of nitrogen fixation will make the soil fertile.........

The question and choices given are a bit tricky. The correct answer is A because the language of (iv) is deceptive and says "new trees will grow quickly to replace the burnt ones". You have to understand that "new trees" won't grow quickly, you can only sow small plants not trees.

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

How ??? It should be b.As ash is an organic matter. the process of nitrogen fixation will make the soil fertile . Please tell .Why????

B IS THE CORRECT ANSWER AS BURNING OF WASTE CROPS AFTER HARVESTING OF GRAINS IS STANDARD METHOD OF INCREASING SOIL FERTILITY
