Basic Needs Of Living Things

Living things have many different needs. Birds need twigs to build a nest, fish need water to survive, your pet hamster needs a clean cage, and plants need sunlight to make food. All around us, living things are using their environment to fill these needs.

Living things often use other living things to satisfy needs, such as in the example of a lion, who uses his prey as food, or the bacteria in your body, which uses you as shelter. Other times, living things use non-living things to fulfill their needs. This might be the lizard who uses a crack in a cliff side to hide, or plants who use minerals from the soil to create food.

All life forms have different needs. For example, most fish do not fly, and most birds do not swim, while most plants don't do either. However, all life forms do have a few of the same basic needs in common. Almost all living things need energy, food, water, oxygen, space, and the ability to maintain homeostasis.
