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

Ans 2:

Class : Class 5
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.........

Ans 3:

Class : Class 9
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

SOF is giving wrong answers ! Does it ever thinks that by reading wrong things , we can get lesser marks in our exams ?!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

Ans 7:

Class : Class 6
B should be the correct answer

Ans 8:

Class : Class 8
WHAT! B is correct, not A. The answer is B, NOT A!

Ans 9:

Class : Class 6
i think it should be B..as ash acts as a fertilizer.

Ans 10:

Class : Class 5
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.

Ans 11:

Class : Class 7
I agree with Ishan as trees cannot grow very quickly...But I did B at my first attempt

Ans 12:

Class : Class 7
The answer should be B.

Ans 13:

Class : Class 7
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

Ans 14:

Class : Class 8
Answer must be B as it is organic and increases soil fertility.

Ans 15:

Class : Class 9
B is the correct answer

Ans 20:

Class : Class 4
I think B is the correct answer

Ans 21:

Class : Class 5
How ??? It should be b.As ash is an organic matter. the process of nitrogen fixation will make the soil fertile . Please tell .Why????

Ans 22:

Class : Class 5
It is certainly B as ashes of any organic matter makes soil fertile.

Ans 23:

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 24:

Class : Class 6
I think the answer should be b as after a forest gets destroyed by a forest fire ,new trees will grow as the remain of the trees will decompose and make the sol fertile.

Ans 25:

Class : Class 9
Ash is an organic matter so the answer should be B

Ans 26:

Class : Class 9

The answer is (c) Condition 1- There should be an area which includes all the shapes [options (b), (c) and (d) satisfy this condition] Condition 2- There should be an area which includes only the circle and triangle [only option (c) satisfies this condition] Therefore option (c) is correct

yes c is correct kindly rectify

Ans 2:

Class : Class 7
Why C is incorrect answer? During Summer month at noon there will be shadow exactly under feet.

Ans 3:

Class : Class 6
The answer should be C.

Ans 4:

Class : Class 6
I think it's option B, as at noon we do have a shadow although it's very small, it's not like there's no shadow at all. If my answer is wrong, kindly rectify

Ans 5:

Class : Class 7

Ans 6:

Class : Class 8
I suppose that option'B' is the correct answer. If my thinkings are wrong, then please kindly make me understand with a reason i understand in simple words. If my answer is correct then please, please, please comment on it. My goal here is not to give long lectures, but to find the correct answer to this question.

Ans 7:

Class : Class 9
It should be (b) because (c) shows that there is no shadow at noon, however even in summer, there is a small shadow at noon. Therefore the answer should be (b).
