Sloths hide in trees to avoid predators and feed on leaves

Today, there are six species left living in the rainforest canopies of Central and South America.Hanging out in the trees is a good way to avoid predators,and there are plenty of leaves to eat.But this diet has its drawbacks.Animals extract energy from food and use that energy to move around,maintain their body temperature,keep their organs working,and all the other activities necessary for survival.But leaves don't contain much energy,and that which they do have is tough to extract.
