Answer:
c. More oxygen and less carbon dioxide
Explanation:
The composition of air in the layers between the soil is called soil atmosphere or gas.
The maximum percentage of gas in soil is nitrogen with 79.2 %. Then it is oxygen with 20.6 % and the last is carbon dioxide with 0.25 %. These gases are required in order to maintain life under the ground. The roots of trees and the microorganisms require soil atmosphere to carry out their functions.
It is the process of movement of substances from a region of higher concentration to a region of lower concentration .

- It does not utilises energy .
<span>Embryonic tissues or germ layers develop during the gastrulation stage.</span> <span>Gastrulation is a process in embryonic development during which the single-layered blastula is reorganized into a three-layered(or two-layered) structure called the gastrula. <span>Two primary germ layers(embryonic tissues) are an inner layer-endoderm and an outer layer-ectoderm. Endoderm and ectoderm interact and produce a third layer-mesoderm. Gastrulation is followed by organogenesis, three germ layers will give rise to specific tissue and organ.For example, ectoderm gives rise to epidermis and nervous system, endoderm to the digestive system and mesoderm to muscles, bones…</span></span>
