According to the figure, the optimal foraging strategy predicts the predator should preferentially hunt:

  • A

  • B

    Optimum-sized prey (highest net energy)

  • C

    Whichever prey is encountered first

  • D

    The smallest prey that are easy to catch

Explanation

Optimal foraging theory predicts predators target prey size that maximizes net energy gain (energy intake minus handling/search costs).
