Question

using the 10% rule when studying trophic pyramids, if the producers produce 1000 joules of energy, 100 joules will be passed on to the herbivore. how much energy is passed on to the secondary consumers? 0.1 joule 75 joules 10 joules

Explanation:

Step1: Recall the 10% rule

The 10% rule states that only about 10% of the energy from one trophic level is passed to the next.

Step2: Identify energy at herbivore level

Herbivores (primary consumers) have 100 Joules (from 1000 Joules of producers, 10% of 1000 is 100).

Step3: Calculate energy for secondary consumers

Secondary consumers get 10% of the herbivore's energy. So, 10% of 100 Joules is \( 0.1 \times 100 = 10 \) Joules.

Answer:

10 Joules
