Many of these organisms live in extremely hot or salty water?

Archaea are unicellular, prokaryotic microorganisms that differ from bacteria in their genetics, biochemistry, and ecology. Some archaea are extremophiles, living in environments with extremely high or low temperatures, or extreme salinity. Only archaea are known to produce methane.

What organisms live in extremely hot or salty water?

An organism that lives in a very salty environment is called a(n) . Archaea that live in salty environments are known as halophiles. Archaea that live in extremely hot environments are called thermophiles. Archaea that produce methane are called methanogens.

What does the existence of life in such extreme environments say about the possibility of life on other planets?

Extreme environments on Earth may be similar to those found on other planets. The fact that life probably evolved and continues to flourish in such extreme environments here on Earth suggests that some form of life may have evolved on other planets.

How many types of living things do we have?

Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.

Is the specific process by which microbes carry out the decomposition of harmful chemicals?

Factors affecting microbial bioremediation

Bioremediation is involved in degrading, removing, altering, immobilizing, or detoxifying various chemicals and physical wastes from the environment through the action of bacteria, fungi and plants.

Where do Archaeans live?

Where are archaea found? Archaea were originally only found in extreme environments which is where they are most commonly studied. They are now known to live in many environments that we would consider hospitable such as lakes, soil, wetlands, and oceans. Many archaea are extremophiles i.e lovers of extreme conditions.

Where do bacteria live?

Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow. Some live in or on other organisms including plants and animals including humans. There are approximately 10 times as many bacterial cells as human cells in the human body.

Why some organisms or living things can live in extreme conditions on Earth?

Some organisms have developed strategies that allow them to survive harsh conditions. Almost all prokaryotes have a cell wall, a protective structure that allows them to survive in both hypertonic and hypotonic aqueous conditions. ... These are prokaryotes that can tolerate very high doses of ionizing radiation.

What organisms can live in extreme conditions?

Archaea is the main group to thrive in extreme environments. Although members of this group are generally less versatile than bacteria and eukaryotes, they are generally quite skilled in adapting to different extreme conditions, holding frequently extremophily records.

Can life exist in extreme environments?

An organism that thrives in an extreme environment is an extremophile; in more than one extreme it is a polyextremophile. Examples of the latter would include Sulfolobus acidocaldarius, an archaea that flourishes at pH 3 and 80 °C (Fig. 1).

What are living organisms?

An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. An organism would, therefore, be any animal, plant, fungus, protist, bacterium, or archaeon on earth. ... Organisms can also be classified according to their subcellular structures.

Are there two kinds of living organisms in the world?

Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea. All types of organisms are capable of reproduction, growth and development, maintenance, and some degree of response to stimuli.

What process do microorganisms use to break down pollutants?

Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source.

Why microorganisms are used in bioremediation?

Bioremediation refers to the use of microorganisms to degrade contaminants that pose environmental and human risks. Bioremediation processes typically involve the actions of many different microbes acting in parallel or sequence to complete the degradation process.
