1 Answer

Answer :

Here we will use the 10% law of transfer of energy. As, it is given that 100 J of energy is available to lion. Let the amount of enrgy available to deer be x Joules. According to 10% law, Energy available to lion = 10% of energy of deer             100 J = 10/100 × x ⟹             x = 1000 J Now, let the amount of enrgy available to plants be y Joules. Again applying 10% law, we have: Energy available to deer = 10% of energy of plant             1000 J = 10/100 × y ⟹                y = 10000 J So, the energy available to plants, i.e., producer is 10,000J.
