Which domain of life seems to be absent for deep-subsurface communities?

Life consists of three domains bacteria, archaea, and eukaryotes. Bacteria and archaea are the two domains which can be found everywhere on the earth. Organisms from these two domains can be found in extreme conditions where eukaryotes cannot survive. These organisms are called extremophiles.

Deep subsurface has some extreme environment like high temperature and pressure where survival of eukaryotes is not possible but organisms from domain archaea and bacteria can flourish there.

These microorganisms have evolved some mechanism like special enzymes and protecting capsules which protect them in extreme climate of deep subsurface.

Therefore the domain of life seems to be absent for deep-subsurface communities is eukarya.

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
