The Basic Needs Of Living Things

Every living organism on earth needs some basic things to survive. The amount, way, form or kind of these needs vary from organism to organism.

For example, water is a basic need for survival. The amount of water a frog needs to survive is not the same as the amount of water a desert cactus plant needs to survive. They all need water, but because they are different living organisms, their water needs will be different, even though they both need water to live.

There are five basic needs that all living things have. They are
water air food temperature sunlight

living things needs
Sunlight: This is probably the most important need for all living organisms, because it is the source of all energy. It also provides heat for plants and animals

living things needs
Water: Water is the medium in which living cells and tissue work. Water is also a living environment for many plants and animals

living things needs
Air: Air is made up of several gases, but the two most important gases are Oxygen and Carbon dioxide. Without oxygen, animals will die, and without carbon dioxide, plants cannot survive.

living things needs
Food (nutrients): Living things need energy for function. Energy is needed to grow, reproduce, move, and to work. Think of what will happen if you stayed for three days without food…

living things needs
A Habitat with the Right Temperature: Too cold or too hot? Every living organism needs the ideal temperature to survive either on land or in water.

Certain factors in a living organism's environment can prevent it from surviving there. Those factors are called
‘limiting factors’. They include soils, temperature, water, sunlight and physical barriers. Physical barriers may include landforms and water bodies. They often prevent a living organism from moving to another place when conditions get bad in their regular habitat.

Now, we shall take a close look at what each need really means and why it is extremely important that they get their living needs.
