These organisms are called heterotrophs.
Photoautotrophs such as all plants are autotrophs. These organisms get their energy from the sunlight via photosynthesis. Some plants, however, live on a poor soil and must get their nitrogen source from animals such as flys and ants. A venus fly trap is an example of this.Chemoautotrophs such as certain bacterium or protozoanare also autotrophs. These organisms get their nourishment through the oxidation of inorganic chemical compounds as opposed to photosynthesis.
They oxidize inorganic compounds as a source of energy.ORChemoautotrophic bacteria uses energy produced by oxidizing or reducing chemical substances. The energy released from oxidation or reduction is used to synthesize organic compounds. Hence they don't need sunlight.This chemosynthesis does not and this is how it differs from photosynthesis.
Synthesis of carbohydrates from carbon dioxide and water using energy obtained by chemical oxidation of simple inorganic compounds. This form of synthesis is limited to certain type of bacteria and fungi.
Inorganic compounds can break down through physical processes such as dissolution, precipitation, or mechanical degradation, as well as chemical processes like hydrolysis, oxidation, or reduction. These breakdown processes can be catalyzed by factors such as temperature, pH, presence of catalysts, or exposure to light.
Thermoacidophiles derive their energy from the oxidation of inorganic compounds such as sulfur or iron. This process produces energy for cellular functions in environments with high temperatures and low pH levels.

The source of energy for chemosynthesis is typically inorganic compounds such as hydrogen sulfide, methane, or ammonia. Chemosynthetic organisms use this energy to convert carbon dioxide into organic molecules, without relying on sunlight like photosynthesis.
Chemosynthesis gets its energy from oxidation of inorganic substance, photosynthesis gets its energy from light. Chemosynthesis could occur just about anywhere there are enough suitable chemicals to oxidize [metabolize], while photosynthesis could occur only when there is sufficient light.
Photosynthesis and chemosynthesis are the two major biological processes that drive the growth of primary producers. Photosynthesis is the process by which plants and some bacteria convert light energy into chemical energy to produce food, while chemosynthesis is a process used by certain bacteria to generate energy through the oxidation of inorganic compounds.
The oxidation number for oxygen in most compounds is -2.
