This represent the flow of energy.

The placement of the arrows in a food chain or food web is very important. The arrows always show the direction of the energy as it is transferred from one organism to another. The flow of energy can also be represented within an energy pyramid.
No. The natural selection is when the best suit fits survive. Therefore is not the idea that as an environment changes.
Step 1: Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and \text{NAD}^+NAD + N, A, D, superscript is converted to {NADH}NADHN, A, D, H.
Step 2:Pyruvate oxidation. Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria. There, it’s converted into a two-carbon molecule bound to Co-enzyme A, known as acetyl CoA. Carbon dioxide is released and NADH is generated.
Step 3:Citric acid cycle. The acetyl CoA made in the last step combines with a four carbon molecule and goes through a cycle or reaction, ultimately regenerating the four carbon starting molecule.
