Question

1. grass has 10,000 calories. how many calories would the grasshopper receive? grass → grasshopper → raccoon → coyote

Explanation:

Step1: Apply energy transfer rule

In an ecosystem, typically about 10% of energy is transferred from one trophic level to the next. Grass is the producer (first trophic level) with 10,000 calories. Grasshopper is the primary - consumer (second trophic level).

Step2: Calculate grasshopper's calories

Using the 10% energy - transfer formula \(E_{next}=E_{previous}\times 0.1\). Here \(E_{previous} = 10000\) (calories of grass). So \(E_{grasshopper}=10000\times0.1 = 1000\)

Answer:

1000
