The difference in an area with high concentration and an area with low concentration is called the concentration gradient.
<h3>
What is Concentration Gradient ?</h3>
A concentration gradient occurs when the concentration of particles is higher in one area than another.
In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
This difference in an area with high concentration and an area with low concentration is called the concentration gradient.
