Consider predators with a choice between two prey types: a big prey 1 which has energy value E1, handling time h1, and search time S1; and a small prey 2 with energy value E2, handling time h2, and search time S2. Accordin g to the optimal fora ging theory, when will the predator preferentially select prey 2?
- 1When E2/h2 = E1/h1
- 2When the abundance of prey 1 and prey 2 are equal
- 3When the abundance of prey 1 is very high
- 4When E2/h2 > E1/(h1+S1)✓
Correct answer
When E2/h2 > E1/(h1+S1)
