how does a fully functioning parachute reduces the velocity at which the parachutist falls

it increases the surface area, meaning there will be more air resistance. more air resistance means more energy is wasted as thermal energy, decreasing the kinetic energy, hence reducing the velocity at which the parachutist falls. x

The parachute provides a large surface area for the parachutist which in turn increases the amount of air resistance they encounter as they fall. his reduces their terminal velocity because it will counteract their weight sooner in the fall as they accelerate (and air resistance increases) to produce a 0 resultant force overall so they will not accelerate any faster.
