actually they create some spaces in between the particles of the soil so that air can pass in and out through the particles ans thus maintains the fertility of the soil. Ex- Earthworm.
Living organisms provide nutrients for the soil.
Organisms and insects help to keep soil healthy. They help break down harmful elements and excrete substances to improve the soil.
Organisms in theground consume organic matter and deposit the remnants as nutrients and minerals in the soil in a form that plant life can more easily absorb. Larger organisms, like small animals, burrow in the soil which increases the airiness of the soil.

First answer: by its shape Second answer: Beneficial soil organisms promote the decay of dead vegetable matter and animal matter, breaking them down to minerals that plants need to grow. Thus beneficial soil organisms make soil more fertile. Harmful soil organisms have the opposite effect, however, producing a stench in wet soils without proper drainage and making them acidic and unfertile.
Bacteria and fungi are types of organisms that are found in soil.

I think this is the answer: Some soil organisms mix the soil and make spaces in it for air and water. Other soil organisms make humus, The material that makes soil fertile.
Living organisms provide nutrients for the soil.
Raw potatoes can be contaminated with Salmonella. Salmonella and other disease-causing organisms are found in soil and potatoes are grown in soil.
Soil colloids have large surface areas which can be used as sights for cation exchange, increasing the soils cation exchange capacity. The higher the cation exchange capacity in a soil, the more the soil is able to retain nutrients because the cations are suspended in the soil and are then able to be used by organisms in the soil.
