Question

The controlled use of fire was the first use of energy in a form other than select one:

a. food.
b. water.
c. biomass. and. wind.

Answer 1

The answer is A. Food has been, since the emergence of life on earth, the first source of energy for organisms. This energy was harnessed through respiration to enable growth and development, movement and also provide heat. Ancient humans then discovered fire and also harnessed its energy to cook food (making food easily digestible) and also warming themselves during winter.
