Question

multiple choice question without the use of energy, matter tends to flow ________. down gradients up gradients

Explanation:

In natural processes, without the input of energy, matter moves from areas of higher concentration, pressure, or potential to areas of lower concentration, pressure, or potential, which is "down gradients". This is due to the principle of entropy - systems tend to move towards a state of greater disorder or equilibrium.

Answer:

A. down gradients
