6. Why is the air present in the soil useful
Answers
The air which is present in the soil
is useful because -
• The soil formation process and the soil nutrients addition process needs the active participation of various microorganisms which are living in the soil. For the survival and the reproduction of these necessary microorganisms,the soil air is extremely necessary.
• The roots of the plant doesn't get any access to the atmospheric oxygen and that's why the roots of a plant is dependent on the soil trapped oxygen. Now, this soil trapped oxygen is contained by the soil air.
Answer:
The air in the soil is necessary to have different locations of biological events. Plants absorb air through their roots; that is, they breathe through them, absorb oxygen, and release carbon dioxide. It is the opposite of the photosynthesis process, in which the leaf absorbs carbon dioxide and releases oxygen, which is necessary for plant cells. Underwater plants like rice actually have air pockets at their roots to be able to breathe.
The air in the soil also allows microorganisms that break down organic matter to live and reproduce. This turns the organic waste into smaller particles, which can benefit the growing plant because the organic matter releases nutrients into the soil.
