Does archaebacteria consume their food?
Archaebacteria are microscopic organisms found in extreme places on earth. … They get their nutrition mostly from absorption photosynthesis and ingestion.
What do archaebacteria consume?
Archaea can eat iron, sulfur, carbon dioxide, hydrogen, ammonia, uranium, and all sorts of toxic compounds, and from this consumption they can produce methane, hydrogen sulfide gas, iron, or sulfur. They have the amazing ability to turn inorganic material into organic matter, like turning metal to meat.
Where do archaebacteria get energy?
(1983) have reported that several extremely thermophilic archaebacteria can live with carbon dioxide as their sole carbon source, obtaining energy from the oxidation of hydrogen by sulfur, producing hydrogen sulfide (H2S). They are thus capable of a new type of anaerobic metabolism, a possibly primeval mode of life.
How do archaebacteria make their own food?
They are often called blue-green bacteria. They can make their own food using chlorophyll and are mostly blue- green in color.
Is archaebacteria heterotrophic or autotrophic?
autotrophic Food: Archaea are autotrophic(make their own food). They use chemical synthesis to make food.
How do eubacteria get nutrients?
Nutrition. A great many of the most familiar eubacteria are heterotrophs, meaning they must take food in from outside sources. Of the heterotrophs, the majority are saprophytes, which consume dead material, or parasites, which live on or within another organism at the host's expense.
Why are archaebacteria autotrophs?
This is the cell structure of the archaebacteria which includes the cell wall that does not contain peptidoglycan. This is part of the class: Halobacteria. This is a type of bacteria that is autotrophic because it feeds itself through photosynthesis. Archaebacteria are unicellular, meaning they contain only one cell.
Are there heterotrophic archaebacteria?
Archaea can be both autotrophic and heterotrophic.
How do bacteria eat food?
Rather than beaks, bacteria employ enzymes, or proteins that help them break down different nutrients to a useable form for energy. Through this process of breaking down and utilizing nutrients for energy, bacteria also produce many byproducts.
Are archaebacteria heterotrophic?
Archaebacteria are both Autotrophs and Heterotrophs. This means that some can create their own food within themselves and others depend on other things to obtain their food. This is the cell structure of the archaebacteria which includes the cell wall that does not contain peptidoglycan.
Is archaebacteria heterotrophic or autotrophic or both?
in the cell. Body structure : Archaea are single-celled organisms ,but they are sometimes found in colonies. Food: Archaea are autotrophic(make their own food).
How are Archaea heterotrophs?
Archaebacteria are unicellular, meaning they contain only one cell. This is part of the class: Methanobacteria. This bacteria is heterotrophic because it feeds itself by metabolizing methane gas and creating energy.
What do bacteria require to transport nutrients?
Nutrient Uptake Bacteria rely on diffusion to move molecules into the cell through the cytoplasmic membrane.
How do heterotrophic bacteria get food?
Heterotrophic bacteria, which include all pathogens, obtain energy from oxidation of organic compounds. Carbohydrates (particularly glucose), lipids, and protein are the most commonly oxidized compounds. Biologic oxidation of these organic compounds by bacteria results in synthesis of ATP as the chemical energy source.
Is archaebacteria autotrophic or heterotrophic?

Are archaebacteria and eubacteria heterotrophs or autotrophs?
The six Kingdoms
| A | B |
|---|---|
| Archaebacteria | prokaryote or eukaryote; autotrophic or heterotrophic; unicellular; found in the hot spots of the ocean; some are helpful; ancient |
| Eubacteria | prokaryotes; autotrophic or heterotrophic; unicellular; could be good or bad bacteria |
| Response | the reaction to a stimulus |
How are the archaeans feed themselves?
Archaea are like bacteria – they are single cells that don't have a nucleus – but they have enough differences from bacteria to be classified all by themselves. They do things pretty much like bacteria in general – they transport food molecules into themselves through protein pumps or channels in their outer membranes.
How bacteria grow and its nutrient needs?
For growth and nutrition of bacteria, the minimum nutritional requirements are water, a source of carbon, a source of nitrogen and some inorganic salts. Water is the vehicle of entry of all nutrients into the cell and for the elimination of waste products.

How are archaebacteria autotrophic?
Food: Archaea are autotrophic(make their own food). They use chemical synthesis to make food.
How does bacteria get on food?
Microbes can be transferred from one food to another by using the same knife, cutting board or other utensil without washing the surface or utensil in between uses. A food that is fully cooked can become re-contaminated if it touches other raw foods or drippings from raw foods that contain pathogens.
Can archaebacteria be heterotrophic?
Archaebacteria are both Autotrophs and Heterotrophs. This means that some can create their own food within themselves and others depend on other things to obtain their food. This is the cell structure of the archaebacteria which includes the cell wall that does not contain peptidoglycan.
How do bacteria obtain energy without mitochondria?
As with the mitochondrion, a bacterial ATPase lets protons (under the protonmotive force) into the cytoplasm, using them to make ATP. So, though they don't have mitochondria, bacteria can generate energy through glycolysis and by generating a proton gradient across their cell membranes!
Is archaebacteria a autotrophic or heterotrophic?
in the cell. Body structure : Archaea are single-celled organisms ,but they are sometimes found in colonies. Food: Archaea are autotrophic(make their own food). They use chemical synthesis to make food.
Is archaea heterotrophic or autotrophic?
autotrophs Heterotrophs get what they need to survive from other organisms. Most bacteria and archaea are autotrophs. Plants are photoautotrophic.
Can rice become poisonous?
Uncooked rice can contain spores of Bacillus cereus, bacteria that can cause food poisoning. The spores can survive when rice is cooked. If rice is left standing at room temperature, the spores can grow into bacteria. These bacteria will multiply and may produce toxins (poisons) that cause vomiting or diarrhoea.
How do bacteria produce energy?
