- carbon dioxide
 - It decreases
 - scattered light
 - it needs them
 - to move people
 - Evaporation
 - sweating
 - It heats up

Now knowing that electrical current running through a wire causes that wire to heat up and high currents allow too much power, or electrical energy to be wasted in wires in the form of heat, choose the best answer.
