Question

about how much energy would be transferred to tertiary consumers if the producers begin with 25,000 kcal? a 2500 kcal b 250 kcal c 25 kcal d 25000 kcal

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 → Secondary consumers → Tertiary consumers.

Step2: Calculate energy for tertiary consumers

Producers have 25000 kcal.
Primary consumers: \(25000\times0.1 = 2500\) kcal.
Secondary consumers: \(2500\times0.1=250\) kcal.
Tertiary consumers: \(250\times0.1 = 25\) kcal.

Answer:

C. 25 kcal
