Robert is hosting a backyard barbecue. He uses a charcoal fire to grill the chicken. The chicken cooks, but it never touches the
fire directly. What energy transformation occurs as the chicken cooks? A. chemical potential energy → radiant energy → thermal energy B. thermal energy → chemical potential energy → motion energy C. chemical potential energy → electric potential energy D. motion energy → chemical potential energy → motion energy E. radiant energy → electric potential energy → chemical potential energy
When grilling chicken using charcoal fire, the energy transformation that takes place starts from chemical energy, to radiant energy and then thermal energy. The combustion reaction of the charcoal fire converts the chemical energy into heat. The charcoal fire is considered as radiant energy. Lastly, burning fuels like coal or wood produces thermal energy, and that thermal energy is basically the reason why the chicken was cooked even without directly touching the fire.
In this image the bird is eating an insect off of a leaf that is easy to see whereas the insect on the other leaf is camouflaged and still alive. This helps illustrate the concept of natural selection because the camouflage insect is able to survive longer and therefore reproduce more.
