For humans, we have a food chain. For example;
Plants are eaten by Rabbits
Rabbits are eaten by bears
Bears are eaten by some Humans
If the case comes along that the human doesn't eat the bear, there are other food chains, naturally. Either way you will get your energy from what you eat. However, if you were a plant there are different things for energy.
In plants, they have chloroplasts and chlorophyll which then collect energy from sunlight. The sunlight collected either turns into Glucose, STARCH, or it is stored as ATP in the mitochondria of the cell.
Plants and many bacteria, use the sunlight to make food. They then eventually go up the food chain to us, and thus we get the energy to move around or even walk. We have to get the energy from these guys because we don'r get our energy from the sun. Also, pretty much all the things we burn as fuel (gasoline, wood, charcoal, coal, natural gas, etc) originally came from plant sources, which as stated above got their energy from the sun (sometimes millions of years ago). Burning them releases the stored energy.
Our energy comes from the food we eat, which gets converted into glucose and other molecules that our cells use for energy production. The energy in food originally comes from the sun through the process of photosynthesis, where plants convert sunlight into chemical energy.
Roughly 10% of the energy contained in the grass is available for the lion to use. This is due to energy transfer inefficiencies as you move up the food chain, with most of the energy being lost as heat during metabolic processes.
Yes, the energy in food initially comes from the sun as plants use sunlight to convert it into chemical energy through photosynthesis. When animals eat plants or other animals, they obtain this stored energy and use it for their own energy needs.
We use energy most for transportation, electricity generation, and heating/cooling buildings. These sectors account for the majority of global energy consumption.
99.999% of all energy that humans use is originally form the Sun.

Chemical energy and electrical energy are the most widely used energy forms.
The energy that you get from eating plants like lettuce originally comes from the sun. Plants use sunlight to convert water and carbon dioxide into energy through a process called photosynthesis.
the most important use of solar energy is to make electricity.
Roughly 10% of the energy contained in the grass is available for the lion to use. This is due to energy transfer inefficiencies as you move up the food chain, with most of the energy being lost as heat during metabolic processes.
The energy released in a forest fire originally comes from the sun. Trees and other plants use sunlight to photosynthesize and grow, storing energy in the form of carbohydrates. When a fire occurs, these stored carbohydrates are released as heat and light energy.
The petrol we use in our cars in produced by the distillation of crude oil. We also use natural gases for heat. Coal, Oil, and natural gases are called fossil fuels because they were formed from plant and animal remains.

Mechanical energy drives the bus forward, which is produced in the engine from the chemical energy in the fuel, and the lights use electrical energy. The chemical energy in the fuel originally comes from the Sun.
