Non-living things are objects that do not have life. They do not grow, reproduce, or respond to stimuli like living organisms do. Examples of non-living things include rocks, water, and buildings. These items are made of matter but lack biological processes. Non-living things can be classified into two categories: natural and artificial. Natural non-living things are found in nature, such as soil and air, while artificial non-living things are created by humans, like furniture and machines. Both types play important roles in our environment and daily lives.
