All the green plants and photosynthetic microbes produce their food by photosynthesis procedure and all other organisms placed at higher levels in food chain get the energy from them.
Some "Chemo synthetic" bacterium species get energy from chemical reactions,but for that the coordination from photosynthetic reaction is required.
So,we can't imagine the living world possible without the sun.
well the sun provides plants with light and heat energy for photosynthesis to take place. herbivores then eat plants as food, carnivores later eat the herbivores for food and then omnivores eat both plants and animals for food for energy.
The Sun is the main and most important energy source.
The chemical energy used by most organisms for metabolism and growth ultimately comes from _
chemical energy, mechanical energy, and electrical energy
By light, ATP is produced (ATP is the most basic form of usable energy in organisms). Further, during "dark phase", CO2 is incorporated into carbohydrates, thus forming glucose.
If we are able control the fusion reactions then nuclear energy is the most preffered form of energy otherwise solar energy is prefferable.
All living organisms are composed of one or more cells.
The source of energy for most organisms is chemical energy and sunlight.
The organisms that produce the most energy are plants. These organisms are autotrophs which means they can produce their own energy from the Sun.
The most important idea of the law of conservation of energy is that however and how much it is spent, energy is not lost nor destroyed, but only changes form.
ATP
From Food
energy in the form of adenosine triphosphate (ATP)

The original energy in most ecosystems enters through sunlight. Sunlight is captured by plants through the process of photosynthesis, where they convert sunlight into chemical energy. This energy is then passed on to other organisms when they consume the plants or other organisms that have consumed plants.
Autotrophic organisms are animals or plants that can create their own energy from the Sun. The organelle most common in these organisms are chloroplasts.
From the Sun.
