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 with
heterotrophs
and autotrophs, read the following:
Living organisms
require organic compounds for 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 Prokaryotes
There 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 Prokaryotes
The 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) + O2
The 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 the plasma membrane called thylakoids. Many of the molecules needed in the reactions of photosynthesis are found within the thylakoid membrane.
Chemosynthetic Prokaryotes
Chemosynthetic 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 Prokaryotes
Heterotrophic prokaryotes feed on organic matter by secreting enzymes and absorbing the digested material.
Most heterotrophic prokaryotes are aerobic.
Feeding
Three 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

Prokaryotes are also classified according to how they obtain energy and what?
Hydrogen bombs
How do prokaryotes conserve energy?
Prokaryotes conserve energy and resources by regulating their activities
What is a prokaryote that obtains both energy and carbon as it decompses dead organisms?
Prokaryotes that obtain energy and carbon as they decompose dead organisms are categorized as both heterotrophs and chemotrophs. This means they obtain their energy from more complex organic substances, and that they gain energy from electron donors.
What four characteristics are used primarily to identify prokaryotes?
list 4 factors that are used to identify prokaryotes What are four characteristics used to identify prokaryotes? Their shape The chemical nature of their cell walls The way they move The way they obtain energy A fifth is also gram stain
How do autotrophs obtain energy?
Autotrophs obtain energy by the sun, or chemicals in sunless environments, and Heterotrophs obtain energy by the foods they consume

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 four groups into which prokaryotes are divided based on the ways they obtain energy?

Why do prokaryotes have a great diversity?
Prokaryotes have diversified greatly throughout their long existence. The metabolism of prokaryotes is far more varied than that of eukaryotes, leading to many highly distinct prokaryotic types. For example, in addition to using photosynthesis or organic compounds for energy, as eukaryotes do, prokaryotes may obtain energy from inorganic compounds such as hydrogen sulfide. This enables prokaryotes to thrive in harsh environments as cold as the snow surface of Antarctica, and as hot as undersea hydrothermal vents and land-based hot springs.
