Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated. This process is called diffusion.

Explanation:

Diffusion is a frequent way of transporting substances through the cell membrane. In the diffusion process, the molecules of a region of high concentration tend to move to an area of low concentration until it is equal throughout a space, due to the kinetic energy of the molecules.

This movement of molecules depends on the thermal energy of a particle system and the difference in concentration between the two regions or areas, so that the net flow of particles from a region more concentrated to another less concentrated can be understood as simple diffusion or passive particle transport. In the case of cell membranes, simple diffusion depends on the concentration and the type of molecule to be transported.

This process is called diffusion

Explanation:

More facillitated diffusion, because it moves from high to low concentrated areas, see 7th grade science textbook.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
