If the following equation (where E=energy gained, h=handling time, and S=search time) is an accurate representation of the rate of return for two prey types, which one (prey type 1 or prey type 2) should the individual eat?
$\underline{E_1} \underline{E_2}\
H_1~~~S_2+h_2
$
A) Prey type 1
B) Prey type 2
C) Either prey type 1 or 2; their rates of energy gain are essentially equivalent.
D) Neither; they both will inevitably require more energy to consume than they will provide.

Question

If the following equation (where E=energy gained, h=handling time, and S=search time) is an accurate representation of the rate of return for two prey types, which one (prey type 1 or prey type 2) should the individual eat?
$\underline{E_1} > \underline{E_2}\
H_1~~~S_2+h_2
$
A) Prey type 1
B) Prey type 2
C) Either prey type 1 or 2; their rates of energy gain are essentially equivalent.
D) Neither; they both will inevitably require more energy to consume than they will provide.

The equation suggests that the rate of energy gain for prey type 1 is greater than that for prey type 2, indicating that prey type 1 should be eaten for a higher rate of return.
