Detailed explanation-1: -Soil is generally porous (though some soils more so than others). This means that air is usually able to diffuse into the soil. There is biomass in the form of living organisms, which transfer throughout the soil as they are mobile, and can help move materials around within the soil. This is known as biological mixing.

Detailed explanation-2: -The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air.

Detailed explanation-3: -Translocation involves the movement of soil-forming materials through the developing soil profile. Translocation occurs by water running through the soil transferring materials from upper to lower portions of the profile. Burrowing animals like earth worms, ants, etc., move soil materials within the profile.

Detailed explanation-4: -The biological component includes the plants, animals, insects, earthworms, nematodes, arthropods, protozoa, fungi, and bacteria that live in the soil. The biological community is a very important component of soil health.
