Where does all the energy in a food chain come from at the start?
AFrom the soil
BFrom the air
CFrom the rain
DFrom the Sun
Answer & Solution
Correct answer: D. From the Sun
1. Plants trap sunlight and store it as chemical energy in food.
2. Animals that eat plants take in some of that stored energy.
3. Animals that eat other animals take in energy that came the same way.
4. So every food chain traces its energy back to the Sun.
