Ok I see it now, when a plant dies it release energy from decomposition, the compost is mineral rich and supplies new plants with energy, energy is then used to create more cells in a plant. Got it. One question, since the population is rising does that mean that plant life will always deplete and eventually run out? Does that mean that we can never have an abundance of plant life?
True but that is not a stipulation of the law of conservation of energy. Ultimately, as long as the sun shines, enough energy will be provided to the Earth for us humans to perpetuate our wasteful and destructive habits.blimkie said:however if we continue to remove plants for various reason such as food and lumber faster than we can replace them we will eventually deplete our land

Not necessarily, the 1st Law says that energy/matter is just conserved. Humans can "deplete" themselves by changing too much of something into something else that we can't use. Luckily, like a previous post said, humans are smart, and would rapidly develop new technologies to supplement this loss of something, or just get it some other way.it is basically impossible to deplete ourselves here on Earth because of the sun.
The first law of thermodynamics is the principle of energy conservation, which states that energy cannot be created or destroyed, but can only be transferred or converted from one form to another.
The first law of thermodynamics applies to everyday life in many ways, such as the energy we consume through food and the energy we use to power our homes and vehicles. It also explains how energy is converted from one form to another, such as the chemical energy in gasoline being converted to kinetic energy to power a car.
An example of the first law of thermodynamics in action is the process of photosynthesis in plants. The energy from the sun is converted into chemical energy in the form of glucose, which is then used by the plant for growth and other metabolic processes.
The first law of thermodynamics and the concept of entropy are closely related. Entropy is a measure of the disorder or randomness of a system, and the first law of thermodynamics states that the total energy of a closed system remains constant. As energy is converted or transferred, the entropy of the system tends to increase, leading to a more disordered state.
The first law of thermodynamics is a fundamental principle of nature and cannot be violated. However, it is important to note that while energy cannot be created or destroyed, it can be wasted or lost in the form of heat or other forms of energy that are not useful for performing work.
