Question

use the food web below to help you answer this question. using the 10% rule when studying trophic pyramids, if the primary consumers obtain 100 joules of energy, how much energy do the herbivores have? 30 joules 16 joules 100 joules

Explanation:

Step1: Understand the 10% rule

The 10% rule states that only about 10% of the energy is transferred from one trophic level to the next. But herbivores are primary consumers.

Step2: Analyze the energy level

Since herbivores are primary consumers, and the problem states primary consumers obtain 100 Joules of energy. So herbivores (as primary consumers) have 100 Joules.

Answer:

100 Joules
