By the oxidation of electron donors in their environment. They live in hostile environments where they get energy from sulfur, iron etc.
The difference is the way they obtain energy. Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). Photoheterotrophs are heterotrophic organisms that use light for energy, but cannot use carbon dioxide as their sole carbon source.
Most get their energy from food. However some very specialized organisms obtain energy from inorganic sources in extreme environments such as undersea vents.
Many bacteria are classified as chemotrophs because they obtain energy by breaking down organic molecules chemically.
Phototrophs are organisms (usually plants) that carry out photosynthesis to acquire energy. They use the energy from sunlight to convert carbon dioxide and water into organic materials to be utilized in cellular functions such as biosynthesis and respiration. chemotroph are organisms that obtain energy by the oxidation of electron donating molecules in their environments. These molecules can be organic (organotrophs) or inorganic (lithotrophs). The chemotroph designation is in contrast to phototrophs which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic.
Chemotrophs are the largest taxonomic group of bacteria. Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments.
By the oxidation of electron donors in their environment. They live in hostile environments where they get energy from sulfur, iron etc.
An autotroph uses co2 as primary carbon source where as chemotroph uses chemicals as primary energy source. Chemotrophs also require a source of organic nutrient, and autotrophs would be considered a photosynthesizer.

The large population of bacteria is called syndrome.

Photosynthesis for phototrophs, or chemosynthesis for chemotrophs.
In most food webs the Sun is the ultimate source of energy. Some food webs start with chemotrophs and in those cases the source of the energy are chemicals often from underwater volcanoes.
Green plants and some bacteria can capture energy from sunlight and chemicals respectively.
Many bacteria are classified as chemotrophs because they obtain energy by breaking down organic molecules chemically.
Chemotrophs are also known as bacteria or archaea that live in hostile environments such as deep sea vents and they are the primary producers in these ecosystems only! Hope this helps! :) xxx
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.
