By human made materials I take it you mean materials that would not exist but for human activity. Fossil fuels by definition have existed for millions of years and were made long before humans existed, similarly for uranium. Wind, solar energy, tidal and wave energy have always existed. I suppose you could include fuels made from crops, so called biofuels. Charcoal is also human made.
The main function of carbohydrates is to provide energy? (True or False)
Digestive and Respiratory
Humans use chemical energy from food substances to convet it into mechanical energy, which is the movement of the body. Energy is the amount of work you do and is measured in joules, J. I hope this helps:)
