Question

Quizplus · Accepted Answer

Organisms contribute to soil formation through various processes. They can stir the soil by burrowing or tunneling, which allows for air infiltration and water penetration. They also degrade organic matter through processes such as decomposition and excretion, which results in the formation of humus. Additionally, organisms contribute organic matter to the soil through their bodies and waste products, which can help to increase the nutrient content and overall fertility of the soil. Therefore, all of the choices listed (stirring soil, degrading organic matter, and contributing organic matter) are ways in which organisms contribute to soil formation.
