Laws of Thermodynamics
First Law of Thermodynamics: total energy in a closed system is neither lost nor gained — it is only transformed
More specifically, the First Law states that energy can neither be created nor destroyed: it can only change form.
Therefore, through any and all processes, the total energy of the universe or any other closed system is constant.
The challenge for all living organisms is to obtain energy from their surroundings in forms that they can transfer or transform into usable energy to do work. Living cells have evolved to meet this challenge very well. Chemical energy stored within organic molecules such as sugars and fats transforms through a series of cellular chemical reactions into energy within ATP molecules.
Humans can convert the chemical energy in food, like this ice cream cone, into kinetic energy (the energy of movement to ride a bicycle).

Chemical equilibrium occurs in both open and closed systems. Most chemical reactions are reversible, meaning endergonic and exergonic reactions can occur in either direction.
