Question

if there were an additional trophic level in this figure that consisted of organisms that prey on snakes, about how much energy would be available to organisms at that trophic level? tertiary consumers 10 kcal secondary consumers 100 kcal primary consumers 1,000 kcal producers 10,000 kcal 1,000,000 kcal of sunlight 100 kcal 10 kcal 90% 1 kcal

Explanation:

Step1: Energy transfer rule

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

Step2: Calculate energy for new trophic level

Snakes are tertiary consumers with 10 kcal. For a new trophic level (preying on snakes), energy is \(10\times0.1 = 1\) kcal.

Answer:

1 kcal
