Question

Quizplus · Accepted Answer

A) Decomposing organic matter: Many organisms, such as bacteria and fungi, break down organic matter, which releases nutrients into the soil for other organisms to use. 
B) Mixing and aeration: Organisms, such as earthworms, burrowing insects, and plant roots, help to mix and aerate the soil, which improves soil structure and nutrient availability. 
C) Leaching soils of nutrients: This is not a role that organisms play in soil. Instead, leaching occurs when water moves through the soil and carries nutrients away. 
D) Recycling soil elements through consumption and waste production: Organisms consume nutrients and other elements from the soil, and then release them back into the soil through waste products. This helps to cycle nutrients through the soil and make them available to other organisms. 
E) Becoming humus: Over time, dead organisms and their waste products accumulate in the soil and become humus, which helps to improve soil fertility and structure.
