Kleiber's Law, Tiger and Tree

Caption: New research suggests that the shapes of both plants and animals evolved in response to the same mathematical and physical principles. By working through the logic underlying Kleiber's Law (metabolism equals mass to the three-quarter power) and applying it separately to the geometry of plants and animals, researchers were able to show that plants and animals display equivalent energy efficiencies.
