If 200, 000 kJ of energy is available to the producers, how much energy is available to the secondary consumers in this food pyramid?

2,000 kJ
20,000 kJ
20 kJ
200 kJ

1 answer

The energy available to the secondary consumers in this food pyramid can be estimated by using the 10% rule. According to this rule, only 10% of the energy from one trophic level is transferred to the next.

Let's calculate:
Energy available to secondary consumers = 0.1 * Energy available to producers
Energy available to secondary consumers = 0.1 * 200,000 kJ

Energy available to secondary consumers = 20,000 kJ

So, 20,000 kJ of energy is available to the secondary consumers in this food pyramid.
