They divide the amount of people by square miles

The second law of thermodynamics states that not all of the energy is used because some of the energy is lost in the form of heat. The lost heat energy is an unusable form of energy, and it causes an increase in the entropy of the universe. Thus, no energy transfer process is efficient due to the loss of energy.
Exchange of gases in fish is very efficient because of: the large surface area of the gills. the large surface area of the blood capillaries in each gill filament. the short distance required for diffusion – the outer layer of the gill filaments and the capillary walls are just one cell thick.
