FACILITATED DIFFUSION.
Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).
Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.
Answer:Exercise increases the rate at which energy is needed from food, increasing the need for both food and oxygen by the body. This is why when we exercise both pulse/heart rate and breathing rate increase.
