How do prokaryote get energy?
Prokaryotes are unicellular microorganisms that do not have a nucleus. Some prokaryotes obtain energy by consuming organic molecules made by other organisms, while others manufacture their own food from inorganic molecules.
What are the food molecules made of?
An example of a common inorganic molecule found in foods would be NaCl (salt). Halogens bonded to metals do not fit the definition of organic molecules, thus making them inorganic. Water is another example.
What is the difference between Inorganic and Organic Food?
In general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions).
Why are producer organisms called autotrophs?
Autotrophs, or "self-feeders", sustain themselves without feeding off of energy derived from other organisms. Instead, they obtain their own food from inorganic substances using light or chemical energy.Autotrophs are generally known as the producers of the biosphere since they produce organic molecules (i.e. CO2 and H2O) and other inorganic molecules. This allows them to sustain and provide food for heterotrophs, or "other feeders" as well.**Examples of Autotrophs: plants, algae, some prokaryotes, some other protists
What are some way that prokaryote obtain energy?
Living organisms require organic compoundsfor food. Organic refers to molecules that contain carbon and hydrogen. Examples of organic nutrients are carbohydrates (sugars, starches), lipids, and proteins.Autotrophs are organisms that make their own organic food. Heterotrophs consume food that is already present in the environment. For example, plants are autotrophs because they make their own food by photosynthesis. Animals are heterotrophs because they obtain their food by eating it.Autotrophic ProkaryotesThere are two kinds of Autotrophic prokaryotes. Those that make organic food using energy from sunlight are photosynthetic. Autotrophs that make organic food using energy from inorganic chemicals are chemosynthetic.Photosynthetic ProkaryotesThe first photosynthetic prokaryotes to evolve did not produce oxygen.Cyanobacteria evolved later with the same kinds of chlorophyll found in plants. During photosynthesis, water (H2O) molecules are split and O2 molecules are released. The balanced equation is below.Energy + CO2 (carbon dioxide) + H2O becomes C6H12O6 (glucose) + O2The green sulfur bacteria and purple sulfur bacteria do not split water during photosynthesis. Instead, they split H2S; oxygen is therefore not released.Photosynthetic prokaryotes have extensions of theplasma membrane called thylakoids. Many of the molecules needed in the reactions of photosynthesis are found within thethylakoid membrane.Chemosynthetic ProkaryotesChemosynthetic prokaryotes obtain energy to make their organic food by oxidizing high-energy inorganic compounds (hydrogen gas, ammonia, nitrites, and sulfides) instead of consuming organic nutrients or using sunlight.Many chemosynthetic prokaryotes are anaerobic; they are often found deep in the sediments of lakes and swamps.Chemosynthetic prokaryotes form the basis of the food chain for some communities 2.5 km beneath the sea. Energy for these communities comes from hydrothermal (volcanic) vents. The hot water pouring out of these vents contains high concentrations of inorganic minerals such as sulfides that can be used as an energy source by the prokaryotes.Heterotrophic ProkaryotesHeterotrophic prokaryotes feed on organic matterby secreting enzymes and absorbing the digested material.Most heterotrophic prokaryotes are aerobic.FeedingThree types of heterotrophs are described below. Each category is determined by the feeding mode.Saprotrophic organisms are decomposers. They play a critical role in recycling (releasing) nutrients that are tied up in the bodies of dead organisms. Most heterotrophic prokaryotes fall into this category.Parasites are organisms that live in close association with another species and one species benefits at the expense of the other. Usually, the smaller species resides within a larger species and derives its food from the larger organism. Normally, the larger organism is not killed.Mutualistic organisms are those that live in close association with another species and both species benefit as a result of the association. For example, some nitrogen-fixing bacteria live in nodules on the roots of plants. They convert atmospheric nitrogen (N2) to a form that is usable by plants. Plants provide the bacteria with carbohydrates
Are prokaryotes mostly heterotrophic?
In spite of their relatively simple structure, prokaryotic cells have much greater metabolic diversity than eukaryotic cells. Although most prokaryotes are heterotrophs, some are autotrophs. Autotrophs can manufacture their own food (organic molecules) from inorganic substances, while heterotrophs cannot. Most autotrophic bacteria are photosynthetic (they use light energy to manufacture organic molecules) but some are chemosynthetic (they use energy from inorganic chemicals to manufacture organic molecules.)
How do prokaryote get energy?
Prokaryotes are unicellular microorganisms that do not have a nucleus. Some prokaryotes obtain energy by consuming organic molecules made by other organisms, while others manufacture their own food from inorganic molecules.
Do plants need food?
They don't need food as we know it, but they need inorganic molecules to produce glucose and oxygen in the process of photosynthesis.
What are the food molecules made of?
An example of a common inorganic molecule found in foods would be NaCl (salt). Halogens bonded to metals do not fit the definition of organic molecules, thus making them inorganic. Water is another example.
What is an organism called that manufactures its own food?
Organisms that synthesize their own organic compounds from inorganic ones are called autotrophs.The phenomenon is autotrophy; green plants and some other organisms perform it by photosynthesis, while some prokaryotes perform chemosynthesis, synthesizing organic substances using energy not from light but from inorganic chemical reactions.When discussing ecosystems, autotrophs are called producers.
What is the difference between Inorganic and Organic Food?
In general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions).
What is an organism that obtains organic food molecules by eating other organisms or their by products and that cannot synthesize organic compounds from inorganic materials?
Heterotoph
What produces its own food?
An autotroph is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions (chemosynthesis). They are the producers in a food chain, such as plants on land or algae in water.
Why are producer organisms called autotrophs?
Autotrophs, or "self-feeders", sustain themselves without feeding off of energy derived from other organisms. Instead, they obtain their own food from inorganic substances using light or chemical energy.Autotrophs are generally known as the producers of the biosphere since they produce organic molecules (i.e. CO2 and H2O) and other inorganic molecules.

What is an organism that obtains organic food molecules by eating other organisms or their by products and that cannot syntheize organic compounds from inorganic materials?
I believe it is an heterotroph.
How do prokaryotes obtain energy?
The prokaryotes obtain their energy from organic matter and inorganic compounds. Prokaryotic cells include bacteria that can decompose dead organic matter, which they then use as a source of energy.Yes, it does have to do withheterotrophsand autotrophs, read the following:Living organismsrequire organic compounds for food.
