Question

if producers receive 1000 units of energy, approximately how much energy is available to primary consumers? 10000 units 100 units 10 units 1 unit

Explanation:

Step1: Recall energy - transfer rule

In an ecosystem, only about 10% of the energy is transferred from one trophic level to the next. Producers are at the first - trophic level and primary consumers are at the second trophic level.

Step2: Calculate available energy

If producers have 1000 units of energy, the energy available to primary consumers is 10% of 1000. So, $1000\times0.1 = 100$ units.

Answer:

100 units
