Question

Calculate the amount of energy available for plant in the following food chain, if lions have 20 J of energy. Plant → Deer → Lion

Answer 1

Hey mate __
The energy passes in food chain by 10 % law.

let x be the energy of deer
So 10% of x = 20 J
10 x/100 = 20
x = 200 J

Now let energy of plants be y
10% of y= x= 200 J
10y/100 = 200
y = 2000 J = Energy of plants
