Explanation:
Detailed explanation-1: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
Detailed explanation-2: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.
Detailed explanation-3: -Diffusion is the movement of particles from high concentration to low concentration in a substance. This process is essential for life on Earth, allowing for the movement of molecular compounds into and out of the cell.
