It is good for agriculture and made up of particles of gravel sand and clay with the addition of organic a material called humus, with 1 in diameter.

Smallest inorganic particle of soil compared with silt and sand. It retains water before drying; it is sticky and not suitable for plant growth. Water moves very slowly. It is often damp and poorly drained, about 0.005 mm in diameter.

Made up of very fine particles of soil and clay, deposited as sediments. It is about 0.05 to 0.005 in diameter.

Inorganic soil particles are larger than clay or silt. Plants do not grow well because water goes rapidly through the spaces between particles and dries quickly. Its size is about 1 mm to 0.05 in diameter.

Light is an important physical factor. Without light, life on Earth would be impossible.

It is an important factor because of its effect on metabolism.

(O2) is another important abiotic factor for many living organisms.

It is the relationship that includes mating, assistance, gorgeousness, and competition. Organisms belonging to the same species must compete with one another for space; food, and mates.
