it depends on whether your starving or not. if not, it comes from food (measured in calories). otherwise, your body's' energy will come from stored fat, stored glucose (often in the liver) and lean body tissue (muscle).
The energy that travels from warm bodies to cooler bodies is heat. Heat transfer occurs through conduction, convection, or radiation, depending on the medium through which the heat is moving.
Our energy needs depend on body mass because larger bodies require more energy to sustain basic functions like metabolism and movement. This is because more tissue and cells need to be supported and fueled by energy in larger bodies. Smaller bodies have less mass to maintain and therefore require less energy.
We store energy in our bodies to use it. Every movement in our body, including simple things like raising our hands require energy. Without energy, we would not be able to do anything. In order to make it more 'convenient', without having to consume food or drinks when we need energy, we store energy in our bodies so that we can use it when we need it.
The energy used by our bodies is stored primarily in the form of carbohydrates, fats, and proteins. These energy reserves are broken down during metabolism to provide fuel for our cells to function properly.
Energy for humans is derived from the food and drinks we consume, which our bodies then convert into usable energy through a process called metabolism. This energy is used by our bodies to carry out daily activities, such as breathing, circulating blood, and moving muscles.

Fossil fuels (hence the name) are natural fuels that come from decayed bodies (humus or fossils) in the earth.
Human bodies use thermal energy in various ways. The most common way is by ensuring that our bodies have the right temperature at all times.

Yes, the liver can effectively utilize ketone bodies for energy production.
The energy for life comes from the food we eat, which is broken down in our bodies to produce a molecule called adenosine triphosphate (ATP). ATP is the primary energy carrier in cells and is used for various biological processes to sustain life.
