Free energy is something all life requires and that free energy is received from the sun. Biological systems utilize free energy and molecular building blocks, to grow, reproduce, and to maintain dynamic homeostasis.
Five things that we get from free energy:
Organization Organization is how we organzie our life. If we aren't organized than that can often lead to death. To maintain that organization, we require a constant supply of energy. That is used to maintain nerves at a static state, and to maintain that order inside our body. Whatever energy is left we use for storage so we can use it up later.
Growth We use free energy throughout growth to help us replace all those cells that are dying throughout our life. We also use that free energy to grow.
Reproduction We use free energy to be able to pass genes into the generation.
Homeostasis which is how we maintain that internal stable environment.
Metabolism We use free energy through a serious of chemical processes known as metabolism. Which like we discussed before is the sum of all chemcal reactions inside the body.
Disruptions
Disruptions to free energy can lead to death, changes to a population, and even to the ecosystem. Thus, can result to a disruption in growth, reproduction, and mess up an organism's homeostasis and metabolism. Which proves how it can lead to a decrease in population.
