Question

Q.20 In the given food chain. Supose the amount of energy at
Fourth trophic level is 10KJ. What will be the energy available
at the prodcer level ?
a) 10KJ (b) 100KJ (c) 1000KJ (d) 10000KJ​

Answer 1

Answer:

No. (D) 10000KJ is correct answer

Explanation:

Let the energy at producer level be X

Now, by Ten Percent Law, we get

10/100×x = X/10 KJ at 2nd trophic level.

Now, at 3rd trophic level,

10/100× X/10 = X/100 KJ

Now again at 4th trophic level,

10/100 × X/100 = X/1000 KJ

According to the question,

x/1000 = 10

=> x = 10000 KJ
