Answer:
78.29%
Step-by-step explanation:
Given,
The total energy received by the plant from the sun = 41250 kcal
The energy transferred to the caterpillar = 8956 kcal
Now,
The energy not transferred = Total received energy - Total transferred energy
Energy not transferred = 41250 - 8956 = 32294 kcal
Thus the percentage of energy not transferred =

Percentage of energy not transferred =

Energy not transferred to the caterpillar = 78.29%.
