why are the water and air is soil important to the organisms that live in it
Answers
Answer:
The oxygen in the air is essential for animals to survive because we use this oxygen to produce energy from the food we eat. The carbon dioxide we breathe out is in turn required for plants to trap energy from the sun and turn it into food.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.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. The soil is formed by the breaking up of rocks by various geological, climatic and biological processes. Soil contains minerals such as Iron, Zinc, Nitrogen compounds, etc. that are all essential to sustaining life. It also holds water and makes it available for plants to use. Soil also contains ores from which we can extract metals such as iron, copper, gold, and aluminum.
