Question

What are constituent of soil? Classify them as biotic and abiotic constituent

Answer 1

"As a whole, soil is made up from four constituents: mineral material, organic material, air and water. There are considered to be three main mineral parts to soil; 'sand', 'silt' and 'clay'. These parts give the soil its 'mineral texture'.
Abiotic and Biotic

Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals.

Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms

Answer 2

Soil is the major contributor of existence of life on planet earth. Soil in made up of various processes like gradual breaking down of rocks. Weathering of rocks helps in the formation of soil by breaking down the rock in to smaller particles.

There are four major constituent of soil. They are

Organic material, mineral material, water and air

Mineral particles: Silt, sand and clay are the major constituent s of mineral particles.

Organic materials: Dead organic materials like dead animals and plants which are decomposed are the major constituent of organic material of the soil.

Here the biotic compounds are the organic materials where the abiotic compounds are the mineral particles.
