Living things are all around us and encompass a wide variety of organisms. The term living things can be broken down into three categories: organisms, CREATURES, and beings. Organisms are any living thing that is made up of cells, such as plants, animals, fungi, and bacteria. CREATURES are any living thing that is capable of movement, such as animals, birds, and insects. Beings are any living thing that has consciousness, such as humans, animals, and some plants. All of these living things are essential to the functioning of our planet.
