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? 16 joules 100 joules 30 joules

Explanation:

Step1: Identify the trophic level relationship

Primary consumers are herbivores (they eat plants, producers). So the energy of primary consumers (herbivores) is given as 100 Joules. Wait, maybe a mis - understanding? Wait, no - wait, the 10% rule is about energy transfer between trophic levels. But in this case, primary consumers are herbivores. So if primary consumers (herbivores) obtain 100 Joules, then the energy of herbivores is 100 Joules. Wait, maybe the question has a bit of a wording issue, but primary consumers are herbivores. So the energy of herbivores is the same as the energy of primary consumers here.

Answer:

100 Joules (the option: 100 Joules)
