Is conservation of energy involved in the second law of thermodynamics?

It is assumed as part of the second law, but the second law is really all about what happens to the energy as it changes form. If energy were not conserved (1st Law), then it might be possible to violate the second law by magically creating some energy out of nowhere to allow the work coming out of a system to be equal to the energy input even when some is lost to heat.

What is a 2nd law of energy?
You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.
What are the first and second laws of thermodynamics explain how energy flows through the rainforest?
The First Law of Thermodynamics: (Conservation) Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. The second law of Thermodynamics: In all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state. This is also commonly referred to as entropy. I would imagine that energy flows through a rain forest - as it does in any other location!
What is the need of the second law of thermodynamics?
Second law of thermodynamics used for prove of process reversibility, it provide the concept of system loss capability to perform work. Second law of thermodynamics is an effective tools to debunked pseudo-science in the field of perpetual energy (perpetual magnetic generator) and hoax energy saving scam.
How is the law of conservation of energy related to efficiency?
Efficiency can never be greater than one because it is the ratio between work you got out of the system and the total energy. Because of conservation of energy, the equation ΔE = Q + W reduces to Q + W = 0.
What is matter and energy second law of thermodynamics?
The second law of thermodynamics states essentially that it is impossible for heat to flow from a cooler body to a hotter one, without the performance of work by an external agency. I'm not sure how this relates to your wording of 'matter and energy'.
What scientific principle states that energy can be transferred but that it cannot be created or destroyed?
That is known by two different names: (1) Law of Conservation of Energy, (2) Second Law of Thermodynamics.
Why is the conservation of energy an issue that people must deal with if the first law of thermodynamics states energy is not created or destroyed?
Because the second law of thermodynamics states that any use of energy always results in a decrease in the amount of "useful" energy.
How is the 1st law of thermodynamics related to the conservation of energy?
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
Which would mean that the energy in an isolated system would remain constant law of conservation of matter 1st law of thermodynamics second law of thermodynamics or the atomic theory of matter?
The first law of thermodynamics states that the energy of an isolated system is constant.
What is perpatual motion?
It is the idea of a machine continuously producing energy, without energy input - or producing more energy than what is put into the machine. This would violate the First Law of Thermodynamics (conservation of energy), and in general, it is not believed to be possible. No process is known which violates the conservation of energy. (A "perpetual motion machine of the second kind" would violate the Second Law of Thermodynamics; this is generally believed to be impossible, too.)
What evedence shows a star will burn out?
For a start, the Law of Conservation of Energy. In case you don't know about it, I suggest you do some reading; it will help you understand not only that stars have to burn out, but several other things as well. Actually it would help to know about both the First Law of Thermodynamics (basically the Law of Conservation of Energy), and the Second Law of Thermodynamics.For a start, the Law of Conservation of Energy.

Can energy be produced?
You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known). Nowadays, the law of conservation of energy (or First Law of Thermodynamics) is often derived from Noether's Theorem, but that is some advanced math.You can convert one type of energy to another, but see also the Second Law of Thermodynamics.You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known).

What are the conversion 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.
Why the first and second law of thermodynamics may be states you can not get ahead and you can not break even?
According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.
What are the laws of energy conversion?

The law of conservation of energy states that energy can be created or destroyed as long as it is later converted to a more common form?
No, the Law of Conservation of Energy (a.k.a. First Law of Thermodynamics) states that energy CAN NOT be created or destroyed. Converting energy to a less valuable form is related to the Second Law of Thermodynamics.
Which law of energy has never been broken?
The First and Second Laws of Thermodynamics. (1) Total energy remains constant. (2) Entropy increases. Another way to state this is that useful energy is converted into unusable energy.
