The law of conservation of energy states that "energy can not be created (made) or destroyed (made gone)"
Energy is not lost, it is only transformed.
Photosynthesis is the conversion of light into energy. Digestion is the conversion of food into energy.
Photosynthesis
Combustion.
Potential Energy changes to Kinetic Energy.
The stove itself is not but if it is a wood burning stove, when it is used, the conversion of wood into heat is the conversion of chemical into thermal energy
Let's say that everything is an example of the Law of Conservation of Energy - because this is a law that has never been seen to fail. More specifically, in any energy conversion, one type of energy gets reduced; another type of energy inreases in the same amount.
The law of conservation of energy might apply to an energy conversion that you observe in your daily life for example if you have something on the table and you push it or move it with your arm
the first law of thermodynamics
Any time there is an energy conversion, a certain amount of one type of energy gets reduced, and another type of energy increases. The amounts lost and gained are the same, so total energy is conserved.
More or less - however, any energy conversion is subject to the Second Law of Thermodynamics. A simplified explanation is that there are irreversible processes in nature, and that energy converted to heat can no longer be completely converted to other types of energy.
Those would basically be the First and Second Laws of Thermodynamics. The First Law (energy conservation) states that the total energy can not be increased or decreased. The Second Law imposes some limitations about what conversions are possible.

Energy conversion I would say means converting say thermal energy to mechanical, or mechanical to electrical, or other conversions you can think of. Now some machines do this, like electrical generators, or electric motors which is the same but in reverse. Other machines are just mechanical, like a gearbox for example, mechanical energy in and mechanical energy out. So the word machine is more general, energy conversion devices are a sub-set of machines.
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.
