Answer 1

The correct answer is;There are four basic components of soil that are present in the proper amount.The mineral - this portion of the soil is derived from the bedrock from which it was formed. Some of the mineral particles, such as sand, still consist of rock. They are chemically and structurally the same as the parent rock, but have been ground by weather, water, glaciers, and other natural forces into small pieces.Organic matter-

Living and dead plant and animal matter in various stages of growth and decay constitute the organic part of the soil.Water-soil water enables plants to absorb minerals by first dissolving them. Water is also needed for the physiological and chemical processes of plant growth.Air-Soil with a loose surface and large pores permits air to diffuse easily into it. Entry is limited if the soil is crusted over or compacted.
