We need air for breathing.
Air is a mixture of gases. It provides the body with all the energy it needs to carry out its activities.
During the rainy seasons, organisms that live in the soil, like earthworm come up the soil for air during the rainy season. This is because when it rains, water fills up the vacant spaces and air can not get to the organisms. So, they come to the top of the soil to get air.
