Answer:
Explanation:
Air
Air is a mixture of gases that is composed of 78% Nitrogen, 21% Oxygen and a very small percentage of water vapor and other gases.
Water
Water is called the medium of life. All life on the planet requires water (there are some forms of life that can live without air) because all the chemical reactions that occur in living cells occur using water as a medium. Water is found in large bodies like the ocean, seas, rivers, and lakes. It is also found in the atmosphere as vapour and as a solid in snow, glaciers and ice shelves.
Soil
The minerals useful for life are found in the upper crust of the earth. But most of these are found in rocks, which cannot be used by plants or animal. Instead, we need them crushed in small particles which we call soil.
