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.
The correct answer is letter a. herbivores feed on low-lying plants. Organisms that live in the rainforest have developed unique adaptations that aid in their survival just like <span>herbivores feed on low-lying.</span>
Here are the choices
<span>a.
herbivores feed on low-lying plants b.
birds have beaks adapted to break open hard shells c.
insects have a widely-varied diet d.
plants are able to store water in their leaves</span>
