Most of them do it exactly the same your own cells do it - oxidizing hydrogen in mitochondria.
A few use fermentation (sugar to lactic acid).
Some of the adaptations they develop through Evolution help them acquire energy.

All animals are heterotrophs, getting their organic molecules (food, growth) from another organism. Those that consume other organisms are predators. The larger predatory animals that consume smaller animals are carnivores (meat eaters).
(noun)The act or process of inhaling and exhaling; breathing. Also called ventilationThe act or process by which an organism without lungs, such as a fish or plant, exchanges gases with its environment.The oxidative process occurring within living cells by which the chemical energy of organic molecules is released in a series of metabolic steps involving the consumption of oxygen and the liberation of carbon dioxide and water.Any of various analogous metabolic processes by which certain organisms, such as fungi and anaerobic bacteria, obtain energy from organic molecules.
First of all, autographs and heterotrophs are not even closely related. Heterotrophs obtain energy by consuming organic matter of other organisms, either living or deceased. Autotrophs obtain energy by capturing it from sunlight (photosynthesis) or capturing chemical energy (chemosynthesis).
Respiration
Organic molecules form the structure of all living organisms and derive energy from the organism's environment.
Heterotrophs are organisms that cannot produce their own food and must consume organic matter from other organisms to obtain energy. They get their energy by breaking down complex organic molecules, such as carbohydrates, proteins, and fats, through processes like digestion and cellular respiration.
Organic molecules in unicellular organisms serve as building blocks for cellular structures, provide energy through metabolic processes, and serve as signaling molecules for communication within the cell. These molecules are essential for growth, maintenance, and reproduction of unicellular organisms.
Fungi acquire energy through a process called extracellular digestion, where they release enzymes to break down organic matter in their environment into smaller molecules that can be absorbed. They then use these molecules as a source of nutrients and energy for growth and reproduction.
Organic molecules are consumed by living organisms as a source of energy through processes like cellular respiration or fermentation. This energy is used to fuel various cellular activities and maintain life processes. Examples of organisms that consume organic molecules include animals, fungi, and certain bacteria.
Heterotrophs
Metabolism involves ither using energy to build organic molecules or breaking down organic molecules in which energy is stored. Organic molecules contain carbon.Therefore, an organism's metabolism is part of Earth's carbon cycle.
There are several theories on how the first organisms on Earth obtained energy. The generally accepted theory is that these organisms harvested organic substances from the primordial soup of energy-rich molecules.
Autotrophic organisms, such as plants, algae, and some bacteria, are able to synthesize organic molecules from inorganic raw materials through processes like photosynthesis or chemosynthesis. These organisms can convert energy from sunlight or inorganic substances into organic molecules that serve as food for themselves and other organisms.
Chemolithotrophs are organisms that derive energy by oxidizing inorganic compounds, such as minerals or chemicals, without needing organic molecules for energy. These organisms use this energy to fuel their metabolic processes and do not rely on organic sources for their energy needs.
Organisms make energy readily available by transferring the chemical bond energy of organic molecules to adenosine triphosphate (ATP). ATP serves as the primary energy currency in cells, storing and providing energy for cellular activities. This process is known as cellular respiration.
