The sun
most living things get their energy from the sun, though indirectly. the bottom of the food chain depends on plants, then other animals eat those animals. Through each layer there is less energy being passed along, because most of the energy comes from the sun (and water and oxygen that plants need to produce energy), and is converted into usable energy by plants and the like
Energy is required for living things because they have to have energy to do every other characteristic of life. Living things obtain energy by making it themselves or eating other organisms.
When bonds form during cell processes, energy is released.

The role the sun plays is that it gives energy to different living organisms.
Consumers secure energy from their surroundings. Consumers are organisms that obtain energy by consuming other living organisms, such as plants or other animals. Decomposers, on the other hand, break down dead organisms and organic matter to obtain energy.
Fungi get their energy from living or dead organisms. They will usually specialize in living or dead and it is rare that they can do both.
They obtain their energy by consuming other organisms.
Chemosynthetic organisms are organisms that can produce energy through chemical processes rather than relying on sunlight for energy, like photosynthetic organisms. These organisms are often found in extreme environments, such as deep-sea hydrothermal vents or caves, where sunlight is scarce. Examples of chemosynthetic organisms include certain bacteria and archaea.
Animals.
Heterotrophs must obtain energy through their diets. These organisms cannot produce their own energy through photosynthesis or other means, so they rely on consuming other organisms to obtain the energy they need to survive. Examples include animals, fungi, and some bacteria.
