These plants use the water and nutrients from the soil to grow. Thus, without soil, the plants will not be able to survive and therefore the food chain of the earth will be disturbed. Soil is also useful as a home for many living organisms.<\/p>\n<p>Many small organisms like ants, earthworms, etc. reside in the soil.
