Use diagram to answer. According to the rule of 10 the amount of energy available to owls is

A. 17380kJ + 2527kJ =19907
B.253 kJ (3 sig dig)
C.14039.7 or 140X10⁴ kJ (3 sig dig)
D. 2527 + 17380 + 120500 = 140407 kJ
The diagram shows: an energy pyramid with an owl mice with numbers 2,527kj a grasshopper with the numbers 18,380kj and grain,grasses, and weeds with the number 120,500kj from top down

C. 14039.7 or 140X10⁴ kJ (3 sig dig)

According to the energy pyramid, the amount of energy available to the owls is the sum of the energy from the grasshopper and the mice, which is 18,380 kJ + 2,527 kJ = 20,907 kJ. However, since the answer choices do not match this calculation exactly, the closest option is C, which is 14,039.7 kJ (or 140 X 10^4 kJ) with 3 significant digits.
