Detailed explanation-1: -Soil is composed of both biotic-living and once-living things, like plants and insects-and abiotic materials-nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead.

Detailed explanation-2: -Soil is considered an abiotic factor since it is mostly made up of small particles of rock (sand and clay) mixed with decomposed plants and animals. Plants use their roots to get water and nutrients from the soil.

Detailed explanation-3: -Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.

Detailed explanation-4: -Soil is considered an abiotic factor because it is comprised of small particles of rock, sand, and clay mixed with decomposed plants and animals. Soil types vary, contributing to the environment in different ways. Nutrients are a vital form of sustenance for living organisms.

Detailed explanation-5: -Abiotic factors refer to all the non-living, i.e. chemical and physical factors present in the atmosphere, hydrosphere, and lithosphere. Sunlight, air, precipitation, minerals, and soil are some examples of abiotic factors.
