Explanation:

Environmental microbiology is the science in charge of the study of microorganisms, small living things known as microbes. Study organisms that are only visible through a microscope, such as prokaryotic and simple eukaryotic organisms.

Metagenomics is the study of a collection of genetic material from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. It is generally used when studying microbial communities in which one microorganism cannot be separated from another.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
