Question

how much energy do the tertiary consumers get from the producers if the producers have 785,000 j. 78500 785 7850

Explanation:

Step1: Energy transfer rule

In an energy pyramid, about 10% of energy is transferred from one trophic level to the next. Producers → Primary consumers (10% of producer energy) → Secondary consumers (10% of primary consumer energy) → Tertiary consumers (10% of secondary consumer energy). So the energy transfer from producers to tertiary consumers is \(0.1\times0.1\times0.1 = 0.001\) of producer energy.

Step2: Calculate energy for tertiary consumers

Given producer energy \(E_p=785000\space J\). Energy for tertiary consumers \(E_t=E_p\times0.001\). Substitute \(E_p = 785000\space J\) into the formula: \(E_t=785000\times0.001=785\space J\)

Answer:

785
