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.
That's true because the basic functions of a multi-cellular plant occur in the cell and like any other cell, unicellular alga are also cells thus basic functions such as respiration, excretion, growth occur in both multicellular organisms as well as unicellular organisms
