What does archaea need to grow
Most other living things require at least some kind of organic material to generate energy, so archaea occupy a unique place in the global food web in this regard. Many forms of archaea can use totally inorganic forms of matter—hydrogen, carbon dioxide, or ammonia, for example—to generate organic matter themselves.
How do archaea live
Some archaeans can survive the desiccating effects of extremely saline waters, such as the well-known archaeon Halobacterium, which is a member of the salt-loving group of archaea. Archaeans also thrive in petroleum deposits deep underground.
What do archaea feed on
Archaea can eat iron, sulfur, carbon dioxide, hydrogen, ammonia, uranium, and all kinds of toxic compounds, and from this consumption they can produce methane, hydrogen sulfide gas, iron, or sulfur.Feb 5, 2010
Do archaea need oxygen
Some archaea produce methane as a by-product of their energy production and are called methanogens. Methanogens live, for example, in your intestines, where there is very little oxygen. Most bacteria and archaea dont use oxygen to produce energy and live an oxygen-free (anaerobic) existence.
What feature enables the archaea to survive in harsh environments
Their cell walls are what allow the Archaea to survive in harsh environments.
How do Archaea survive extreme heat
Because hyperthermophiles live in such hot environments, they require DNA, membrane, and enzyme modifications that help them withstand intense thermal energy. Because of these modifications, hyperthermophiles can even survive the autoclave, a device designed to kill organisms through high temperature and pressure.
What are 3 characteristics of Archaea
The following traits are shared by all archaebacteria known to date: (1) the presence of distinctive tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, which is frequently replaced by a predominantly proteinaceous coat; (3) the presence of ether linked lipids made from phytanyl chains; and (4) on August 2, 1978.
Why are archaea more likely to survive in extremely harsh environments than bacteria
All cells have a phospholipid bilayer, but whereas bacteria and eukaryotes have ester bonds in their bilayers, archaea cells have ether bonds, which are more chemically resistant and enable archaea cells to survive in harsh environments that would kill other life forms.
Where do Archaea live
The most extreme of all extremophiles, Archaea are single-celled organisms without nuclei that live in a variety of extreme environments, including the boiling acidic springs of Yellowstone and the icy conditions of Antarctica.
What is a unique characteristic of Archaea
Those archaea that live in extreme habitats like hot springs and deep-sea vents are called extremophiles.
Can Archaea live anywhere
Archaea are a family of single-celled organisms that can thrive in environments like bubbling hydrothermal pools and smoking deep sea vents deep underground, which are too extreme for most other species to survive.

Do Archaea have cell walls
Archaeas cell wall, like that of every other prokaryote, surrounds the cell outside of the cytoplasmic membrane and mediates the interaction with the outside world. In this way, it can be involved in cell shape maintenance, protection from virus, heat, acidity, or alkalinity, or any other number of environmental interactions.
What are 3 characteristics of bacteria
Three distinguishing characteristics of bacteria are: 1) their lack of membrane-bound organelles, 2) their unicellularity, and 3) their small (typically microscopic) size.
What is the importance of Archaea
By carrying out tasks related to nutrient cycling, stress response, and phytohormone biosynthesis as well as by interacting with both bacteria and their hosts, Archaea support the health of the bog ecosystem and the functioning of the vegetation.
Which type of archaebacteria thrive in extreme environments
Thermophiles are archaea that thrive in extremely hot conditions.
What does M Smithii eat
M. smithii, a hydrogenotroph because it consumes hydrogen and a methanogen because it produces methane, helps our digestion by consuming the byproducts of bacterial fermentation.
How are archaebacteria able to metabolize or gain energy
Some bacteria and archaea have metabolic pathways that enable them to metabolize nitrogen and sulfur in ways that eukaryotes cannot. In some cases, these bacteria and archaea use nitrogen- or sulfur-containing molecules to obtain energy, but in other cases, they spend energy to convert these molecules from one form to another.
What are 3 characteristics of eukarya
Eukaryotic cells have the following characteristics: mitochondria; cilia and flagella are the cells locomotory organs; the nucleus is enclosed within the nuclear membrane; and the cell has mitochondria.
