What is the mode of nutrition for protists?
The major modes of nutrition among protists are autotrophy (involving plastids photosynthesis and the organism’s manufacture of its own nutrients from the milieu) and heterotrophy (the taking in of nutrients). See also how was the jaguar important to the maya
How do archaebacteria acquire energy?
Some archaea called lithotrophs obtain energy from inorganic compounds such as sulfur or ammonia. Other examples include nitrifiers methanogens and anaerobic methane oxidizers. In these reactions one compound passes electrons to another in a redox reaction releasing energy to fuel the cell’s activities.
Which kingdoms have autotrophic organisms?
Kingdom Plantae includes multicellular autotrophic organisms.
Archaebacteria – Introduction
How are archaea autotrophic?
Regulation of autotrophic carbon metabolism Many autotrophic archaea are facultative autotrophs or they can co-assimilate organic substrates into cellular building blocks even though they do not use organic substrates as an energy source by oxidizing them to CO2.
Do protists make their own food?
Protists are mostly one-celled organisms. Some make their own food but most take in or absorb food. … Some protists like the one-celled amoeba and paramecium feed on other organisms. Others such as the one-celled euglena or the many-celled algae make their food by photosynthesis.
How are archaebacteria helpful?
So far most archaea are known to be beneficial rather than harmful to human health. They may be important for reducing skin pH or keeping it at low levels and lower pH is associated with lower susceptibility to infections.
Does archaebacteria have a chloroplast?
Archaebacteria like all prokaryotes have no membrane bound organelles. This means that the archaebacteria are without nuclei mitochondria endoplasmic reticula lysosomes Golgi complexes or chloroplasts. … Because these organisms have no nucleus the genetic material floats freely in the cytoplasm.
How do animals obtain their nutrition class 10th?
Animals derive their nutrition either by eating plants directly (herbivores) or indirectly by eating animals which have consumed plants (carnivores). Some animals feed on both plants and animals these animals are termed as omnivores. All organisms require food for their survival and growth.
What is the importance of archaebacteria in our environment?
Recent data suggest that the Archaea provide the major routes for ammonia oxidation in the environment. Archaea also have huge economic potential that to date has only been fully realized in the production of thermostable polymerases.
What period did archaebacteria appear?
Archaeans are an ancient form of life possibly the most ancient. Putative fossils of archaean cells in stromatolites have been dated to almost 3.5 billion years ago and the remains of lipids that may be either archaean or eukaryotic have been detected in shales dating from 2.7 billion years ago.

What is the mode of nutrition in Animalia?
The kingdom Animalia or Metazoa includes all animals. Animals are multicellular eukaryotic organisms which are heterotrophic meaning they obtain nutrition from organic sources. Most animals obtain nutrition by ingesting other organisms or decomposing organic material.
What are the main characteristics of the archaebacteria kingdom?
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs (2) the absence of peptidoglycan cell walls with in many cases replacement by a largely proteinaceous coat (3) the occurrence of ether linked lipids built from phytanyl chains and (4) in …
What are archaebacteria in what ways the archaebacteria has become useful in modern science?
Importance of Archaebacteria Archaebacteria have the capability to produce methane i.e. are methanogens. They do this by acting on the organic matter and hence decomposing it to release methane. Methane can hence for cooking and lighting purposes therefore these bacteria act as primary producers.
Can archaebacteria live without oxygen?
Most bacteria and archaea don’t use oxygen to produce energy and live an oxygen-free (anaerobic) existence. Some archaea produce methane as a by-product of their energy production and are called methanogens. … Other types of archaea can’t live without oxygen just like you. These are called aerobes.
How do organisms obtain their nutrition Wikipedia?
All eukaryotes except for green plants are unable to manufacture their own food: They obtain food from other organisms. … Then the soluble products of digestion for the organism are being broken down for the release of energy (respiration). All heterotrophs depend on autotrophs for their nutrition.
What are the economic importance of archaebacteria?
– Some of the halophilic archaea carry some processes which are economically very important such as biodegradation bioremediation and environmental processes. – Some Thermophilic archaea have enzymes which have an important role in the application of methane production metal leaching and immobilized enzyme systems.
Archaea
Why archaebacteria are considered as ancient bacteria?
Eventually named “archaebacteria” from “archae” for “ancient ” these unique cells are thought to be modern descendants of a very ancient lineage of bacteria that evolved around sulfur-rich deep sea vents.
How do protists get food?
Protists get food in one of three ways. They may ingest absorb or make their own organic molecules. Ingestive protists ingest or engulf bacteria and other small particles. They extend their cell wall and cell membrane around the food item forming a food vacuole.
Is archaebacteria heterotrophic or autotrophic?
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 |

Why the archaebacteria is called living fossils explain its any two groups?
Archaebacteria is called Living Fossils because they are the simplest and oldest living species available on the earth. They survive in all extremities of nature fossils also refers to be primitive in origin. Hence Archaebacteria are referred to as living fossils.
Are archaebacteria consumers or producers?
Kingdom: Archaebacteria -They are producers consumers and decomposers. – They are a group of stationary AND mobile organisms which means that while some can move others can’t.
What type of reproduction does archaebacteria have?
Archaea reproduce asexually by binary fission fragmentation or budding unlike bacteria no known species of Archaea form endospores. The first observed archaea were extremophiles living in extreme environments such as hot springs and salt lakes with no other organisms.

What kind of food do archaebacteria eat?
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.
How do organism of archaebacteria obtain their energy and food?
(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 animals obtain their nutrition?
Animals obtain their nutrition from the consumption of other organisms. Depending on their diet animals can be classified into the following categories: plant eaters (herbivores) meat eaters (carnivores) and those that eat both plants and animals (omnivores).
Where do archaebacteria get their food from?
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.
What kind of cells do archaebacteria have?
Archaebacteria. Archaebacteria are single-celled prokaryotes originally thought to be bacteria. They are in the Archaea domain and have a unique ribosomal RNA type. The cell wall composition of these extreme organisms allows them to live in some very inhospitable places such as hot springs and hydrothermal vents.

Do archaebacteria have nutrition?
Option A – Mode of nutrition in archaebacteria is the same as other bacteria. They are said to have an autotrophic mode of nutrition. … Ether lipids present in the cell membrane of archaebacteria are more resistant this is why they survive in harsh conditions.
Is archaebacteria prokaryotic or eukaryotic?
The archaebacteria are a group of prokaryotes which seem as distinct from the true bacteria (eubacteria) as they are from eukaryotes.
How do archaebacteria maintain homeostasis?
Most bacteria and archaea have mechanisms that maintain their internal cytoplasmic pH within a narrower range than the pH outside the cell termed “pH homeostasis.” Some mechanisms of pH homeostasis are specific to particular species or groups of microorganisms while some common principles apply across the pH spectrum …
How do archaebacteria move?
Archaebacteria move with the help of cilia which are small hair-like structures or with the help of flagella which is a tail-like whip at one end of the Archaebacteria that provides a sense of direction. Some Archaebacteria have two flagella.
