Available Oxygen
Microorganisms can be classified according to their oxygen requirements necessary for growth and survival: Obligate Aerobes: oxygen required. Facultative: grow in the presence or absence of oxygen. Microaerophilic: grow best at very low levels of oxygen.

BeauHumans are classified as obligate aerobes, meaning they require oxygen to generate energy through aerobic respiration. Oxygen is essential for humans to produce ATP, the energy currency of cells, by breaking down glucose in the presence of oxygen. Without oxygen, humans cannot sustain normal physiological functions and would experience serious health issues.

Identify how the oxygen requirements of a prokaryote can affect the types of environments in which it can live?
Prokaryotes vary in their oxygen requirements, with some being strict aerobes requiring oxygen, some being anaerobes that cannot survive in the presence of oxygen, and some being facultative anaerobes that can switch between aerobic and anaerobic metabolism. This affects the types of environments they can live in, such as aerobic prokaryotes thriving in oxygen-rich environments like open air or ocean surfaces, while anaerobic prokaryotes can be found in environments like deep soils, deep-sea vents, or the human gut, where oxygen levels are low or absent.
Which two atoms are most common in the human body?
