Plants Provide Air and Regulate the Water Cycle

Plants bring you oxygen which is a by-product of photosynthesis. Carbon is also stored by plants and they help in keeping a lot of the produced carbon dioxide from burning fossil fuels out into the earth’s atmosphere. The water cycle is also regulated by plants. They help in purifying and distributing the water of the planet. They also help in moving water from the soil to the atmosphere through a method called ‘transpiration.’
