Question

Consider the following food chain

Grass-----deer-----lion

If 10000J of solar energy is available to the grass ,how much energy would be available to the deer to transfer it to the lion?

Answer 1

Answer:

The energy would be available to the deer to transfer it to the lion 100 Joules

Explanation:

According to the law of food chain, only 10% of energy is transferred to the next level in the food chain.

Energy available to grass = 10000 J

=> Energy available to deer = 10 % of Energy available to grass

= 10/100  x  10000

= 1000 Joules

Similarly,

Energy available to lion = 10 % of Energy available to deer

= 10/100  x  1000

= 100 Joules

Hence the energy would be available to the deer to transfer it to the lion 100 Joules
