Answer:
Soil is the basic requirement for any plant or microorganism(that lives on land) to grow and get all the required amount of nutrients from the environment. Because, when a seed is planted inside a specific amount of soil it grows and develop in to a bud having its initial structure well set for having roots at one end and stem at the other, however the soil provides the bud the main protection and support which is required to balance its structure in a proper way or orientation.
As, there are different layers of soil and each layers consists of a different level or amount of components in it and provides different specification to the over all development of plant life.
Explanation:
- Along, with that there are different level of nutrients inside the different samples of soil taken from various regions or areas which makes it more different in nature to support life and give it a chance to grow or develop itself in it. As different species of plant life requires a more different form minerals and constituents to grow in which brings diversity among plant life, as not all of them requires the same sample of soil to grow in.
- Having, the specific structure of molecules in it, the soil also acts as a barrier for the plant life to save it self from any foreign object or pathogen.
