Eubacteria are the most common unicellular organisms; they are found everywhere on Earth.
environment
Earth organisms need essential nutrients, water, oxygen, suitable temperature, and an energy source to live and reproduce. Additionally, shelter or habitat plays a crucial role in providing a safe environment for organisms to thrive.
organisms in the archaea kingdom Prokaryotes
The extremophiles refers to the organisms that thrive geochemically or physically in the extreme conditions that are detrimental to most life on the earth. The organisms that live in the moderate environments are called the neutrophils or the mesophylls.
