What is ‘Environment’?
The environment is our basic life support system. It provides the air we breathe, the water we drink, the food we eat, and the land where we live.
There are two components that come together to make the environment.
Biotic and Abiotic
Biotic The world of living organisms. e.g. plants and animals.
Abiotic The world of non-living elements
e.g. land, buildings, furniture, etc.
