Summary Introduction
To explain:
The reason that organisms do not violate the second law of
Introduction:
The law of thermodynamics states that the energy present in the ecosystem has remained constant and not converted into one form to another. There are two laws of thermodynamics: the law of conservation (first law) and entropy change (second law).

Based on the laws of thermodynamics, energy is never created. Where does a cell get the energy to create ATP?
How do we get energy from the food we eat? Is this an exergonic or endergonic process? Why? How do the first and second laws of thermodynamics play a role in this process? Why is it important to have energy transferred from the food you eat to ATP?
