Question

question 9 of 10
if a snake receives 200 calories of energy from eating a rabbit, how much of that energy would be passed on to a hawk in the following food chain?
aspen → rabbit → snake → hawk
a. 2,000
b. 200
c. 2
d. 20

Explanation:

Step1: Energy transfer rule

In a food chain, only about 10% of the energy is passed from one trophic level to the next.

Step2: Calculate energy passed to hawk

The snake has 200 calories. The hawk is the next trophic level. So the energy passed to the hawk is \(200\times 10\%=200\times0.1 = 20\) calories.

Answer:

D. 20
