Which hypothesis regarding the evolution of hominin bipedalism suggests that this energy-efficient trait arose so that hominins could search for food that was dispersed after climatic changes at the end of the miocene?

Patchy forest.

Explanation:

The patchy forest hypothesis is the second hypothesis that helps to explain the origin of the hominids. The hypothesis was developed by  Peter Rodman and Henry McHenry.

This hypothesis suggest that the evolution of bipedalism is energy efficient in the environment that contain few tress. The patchy forest result in the dispersion of the forest and this might result in the energy efficiency of bipedalism by walking upright and collect their food with hands.

Thus, the correct answer is patchy forest.

it would be the percentage of food eaten by the flock
