An autotroph is an organism able to make its own food. Autotrophic organisms take inorganic substances into their bodies and transform them into organic nourishment. Autotrophs are essential to all life because they are the primary producers at the base of all food chains. There are two categories of autotrophs, distinguished by the energy each uses to synthesize food. Photoautotrophs use light energy; chemoautotrophs use chemical energy.
Photoautotrophic organisms (e.g., green plants) have the capacity to utilize solar radiation and obtain their energy directly from sunlight.
Until recently, scientists held there existed only a few kinds of bacteria that used chemical energy to create their own food. Some of these bacteria were found living near vents and active volcanoes on the lightless ocean floor. The bacteria create their food using inorganic sulfur compounds gushing out of the vents from the hot interior of the planet.
In 1993, scientists found many new species of chemoautotrophic bacteria living in fissured rock far below the ocean floor. These bacteria take in carbon dioxide and water and convert the chemical energy in sulfur compounds to run metabolic processes that create carbohydrates and sugars. A unique characteristic of these chemoautotrophic bacteria is that they thrive at temperatures high enough to kill other organisms. Some scientists assert that these unique bacteria should be classified in their own new taxonomic kingdom.
What else can I help you with?
Is protista autotrophic or heterotrophic?
Protista, with its peculiar nature, has varieties of ways to gain nutrition. Some like algae and planktons are autotrophic, while animal-like protists such as paramecium and stentor are heterotrophic. Still others are classified as being mixotrophic, which means that they are both capable of obtaining food from others and from inorganic sources.
Are bacteria autotrophs or heterotrophs?
Both types of bacteria exist. Some are autotrophic while others are heterotrophic. Most autotrophic bacteria can synthesize their food from substances like hydrogen sulphide. This process is called chemosynthesis and involves the use of chemical substances for the production of energy. Heterotrophic bacteria, in contrast, cannot synthesize their own energy and must consume organic matter for energy. These include decomposing bacteria, or other groups of bacteria that may be symbiotic of parasitic in nature.
Are African violets autotrophic or heterotrophic?
African Violets are plants and make their own food, so they are autotrophs.
Is locus hetertroph or autotroph?
I think you meant locust. They're heterotrophs just like all animals.
Give example of monerans?
The following are descriptions of the 5 kingdoms:KINGDOM MONERA (monerans) -*1 cell*no true nucleus - prokaryote (genetic material scattered and not enclosed by a membrane)*some move (flagellum); others don't*some make their own food (autotrophic); others can't make their own food (heterotrophic)*examples - bacteria, blue-green bacteria (cyanobacteria)
Are all bacteria heterotrophs?
no, some bacteria are heterotrophic and some are autotrophic. Most bacteria are heterotrophic though.
What are the subgroups of moners?
The subgroups of monera are heterotrophic and autotrophic. Heterotrophic are basically the types of bacteria, meanwhile autotrophic is a type of blue-green algae.
Is Steptococcus pneumonia Autotrph or Hetroph?
All the pathogenic bacteria or for that purpose all the bacteria are heterotrophs.
Are moss heterotrophic or autotrophic?
some are autotrophic, some are heterotrophic some are autotrophic, some are heterotrophic some are autotrophic, some are heterotrophic some are autotrophic, some are heterotrophic
What creates lichen?
It's one of these four: heterotrophic algae and autotrophic fungi heterotrophic bacteria and heterotrophic fungi autotrophic algae and autotrophic fungi autotrophic bacteria and heterotrophic fungi But I'm mot sure which.
Are horses heterotrophic or autotrophic?
Heterotrophic.
Are amobea autotrophic or heterotrophic?
Amoebae are heterotrophic.
Is autotrophic the majority of bacteria?
No, autotrophic bacteria are not the majority of bacteria. The majority of bacteria are actually heterotrophic, meaning they obtain their carbon and energy from organic molecules produced by other organisms. Autotrophic bacteria, on the other hand, are capable of producing their own organic molecules using sunlight or inorganic compounds as a source of energy.
Is Light reaction autotrophic or heterotrophic?
it is autotrophic nutrition
Is trichonympha autotrophic or heterotrophic?
Heterotrophic
What autotrophic and heterotrophic components exist?
Autotrophic components are organisms that can produce their own energy through photosynthesis or chemosynthesis, such as plants and some bacteria. Heterotrophic components are organisms that must consume other living things to obtain energy, such as animals and fungi. Both autotrophic and heterotrophic components play important roles in ecological food webs.
How did autotrophic bacteria get food before there were plants and animals?
Autotrophic means that the organism produces it's own food by photosynthesis, or chemosynthesis. if you meant heterotrophic then you forgot, at least, that other bacteria were around to be eaten.
