Question

use the picture below to answer the following two questions. understanding trophic interactions 9 if producers receive 1000 units of energy, how many units of energy do primary consumers receive from one producer? a 1 unit b 100 units c 2000 units d 1000 units e 10 units

Explanation:

Step1: Recall energy - transfer rule

In a food - chain, only about 10% of the energy is transferred from one trophic level to the next.

Step2: Calculate energy for primary consumers

If producers have 1000 units of energy, and primary consumers are the next trophic level, the energy they receive is 10% of 1000. So, $1000\times0.1 = 100$ units.

Answer:

B. 100 units
