Like mentioned previously, the flamingoâs color comes from its diet of bacteria, algae, plankton, shrimp and crustaceans. Their bill is specially designed for the type of food that they eat. For example, the Lesser Flamingo has a deep-keeled bill that is ideal for the intake of algae and diatoms.
The diffusion coefficient D is a function of both temperature and pressure. Diffusion increases with increasing temperature (as molecules move more rapidly), and decreases with increasing pressure (which packs more molecules in a given volume, making it harder for them to move).
Diffusion results from thermal energy -- the constant random motions of colliding molecules. Temperature affects how strong and frequent the collisions are, and molecular weight affects the outcomes of collisions. So the rate of diffusion depends on both of these quantities.
