All small molecules can move down the concentration gradient as water O2, CO2 etc.
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
When molecules move down the concentration gradient, they are moving from an area of high concentration to an area of low concentration. This movement occurs spontaneously to equalize the concentration of molecules in the given environment.
Diffusion only occurs down a concentration gradient. Put a drop of food coloring in a glass of water - you will never see the food coloring spontaneously concentrate. It will always spread down the gradient.
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
Osmosis occurs from an area of higher water concentration to an area of lower water concentration, moving down the concentration gradient.
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
Substances moving down a concentration gradient passively.
Water moves between cells by osmosis, down a concentration gradient.
A cell can overcome a concentration gradient by using active transport mechanisms such as pumping ions or molecules against their concentration gradient. This requires energy in the form of ATP to move molecules from an area of low concentration to an area of high concentration. Additionally, cells can also utilize facilitated diffusion where integral membrane proteins help transport molecules down their concentration gradient.

when the solute passes from a higher solute concentration to a lower solute concentration, it is known as concentration gradient downhill. and the reverse is true for uphill. also, down hill transport requires energy which is derived from ATP. uphill transport is not derived from ATP's rather from the random motion of the molecules themselves.

Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
