which term describes the movement of materials from areas of higher to lower concentrations that does not require energy?
o osmosis
o equilibrium

Explanation:

Active transport is an energy - requiring process that moves materials against the concentration gradient, from lower to higher concentration. Diffusion and osmosis are passive processes (no energy needed) that move materials from higher to lower concentration. Osmosis is the diffusion of water across a semi - permeable membrane, and equilibrium is a state of balance.

Answer:

For the first question: Active transport requires energy and moves materials from areas of relatively lower to higher concentration.
For the second question: osmosis
