Kinetic and Potential Energy of Atoms
Kinetic and potential energy of atoms result from the motion of electrons. When electrons are excited they move to a higher energy orbital farther away from the atom. The further the orbital is from the nucleus, the higher the potential energy of an electron at that energy level. When the electron returns to a low energy state, it releases the potential energy in the form of kinetic energy. (02:25)
Trees provide many animals, including humans, with food. Coconuts are just one of the several nuts and fruits that trees produce that are edible.

Sexual dimorphism in animals
Many animals show sexual dimorphism, or differences between the males and females of that species. These are mostly physical differences, but other differences like songs in male and female birds can also be thought of as sexual dimorphism. Generally, males are more decorated and larger than females, but there are several species of animals in which the females are larger than the males.
