Question

a backpacker climbs a hill. energy is consumed, energy is produced. radiant kinetic and media potential electrical thermal chemical

Explanation:

When a backpacker climbs a hill, the body uses chemical energy (stored in food, converted via cellular respiration) to do work. As the backpacker gains height, kinetic energy (from movement) is converted to potential energy (gravitational potential energy, since height increases). So chemical energy is consumed (used to power the climb), and potential energy is produced (as height and thus gravitational potential energy increases). Also, some energy is lost as thermal energy (heat) due to inefficiencies in energy conversion, but the main consumed is chemical and produced is potential (or thermal could also be a by - product, but for the primary consumed and produced in terms of useful energy change for the climb's height gain, chemical is consumed, potential is produced).

Answer:

Consumed: Chemical energy; Produced: Potential energy (and Thermal energy as a by - product, but the main useful energy change for height gain is potential. If considering the energy from the body's metabolism, chemical is consumed, and as the backpacker moves up, kinetic energy (from movement) is converted to potential energy, and also thermal energy is released. But based on the options, for the first blank (consumed) Chemical, for the second (produced) Potential (or Thermal, but more likely Potential for the height - related energy change). So the filled - in would be: Chemical energy is consumed, Potential (or Thermal) energy is produced. If we take the most relevant for the climb's energy transformation (gaining height), then:

Consumed: Chemical; Produced: Potential

(If the options are as given, and we have to choose from Radiant, Kinetic, Potential, Electrical, Thermal, Chemical:

Consumed: Chemical (because the body uses chemical energy from food to do work); Produced: Potential (because as the backpacker climbs up, gravitational potential energy increases) and also Thermal (because the body generates heat, so thermal energy is produced as a by - product). But if we have to pick one for produced, Potential is more related to the height gain, while Thermal is a waste product. So the answer for the first dropdown (consumed) is Chemical, and for the second (produced) is Potential (or Thermal, but likely Potential in the context of climbing a hill to gain height).)
