Question

calculate the amount of energy available to lionin the following food chain (plant-deer-lion) if plants have 20000J of energy available from the sun

Answer 1

According to 10% rule,

Energy available to plant = 20,000J

So,

Energy available to deer = 10% of 20,000J

= 2000J

Energy available to lion = 10% of 2000J

= 200J.
