Question

in the following food chain if 1 J of energy is available in the lion. how much energy was available to the producer plants eared by dear and dear rated by lion .

Answer 1

According to [math]10\%[/math] law, in a food chain, only [math]10\%[/math] of the total energy is transferred to the next tropic level.

Let the deer have [math]x[/math] Joule of energy. Then:

[math]10\%[/math] of [math]x=100[/math] [math]J[/math]

[math]\therefore[/math] [math]x=1000[/math] [math]J[/math]

Thus the deer has received [math]1000[/math] [math]J[/math] of energy from the plant.

Similarly you can calculate the energy available to the producer as [math]10000[/math] [math]J[/math].

Answer 2

100 Joule energy reqired
