Question

in the ecological pyramid, approximately how much energy is available to primary consumers? select one answer.
41,400 kcal meters squared
32,200 kcal meters squared
4,600 kcal meters squared
460 kcal meters squared
none of these

Explanation:

Step1: Energy transfer rule

In an ecological pyramid, approximately 10% of energy is transferred from one trophic level to the next.

Step2: Calculate energy for primary consumers

Primary producers have \(46000\) kcal \(m^{2}\). For primary consumers, it's \(46000\times0.1 = 4600\) kcal \(m^{2}\).

Answer:

4,600 kcal meters squared
