Question

1. explain why the cyclist must be fed in order to continue to pedal. (complete sentences)

Explanation:

The cyclist needs energy to pedal. Food provides the necessary energy through the process of cellular respiration, which converts the chemical energy in food into ATP (adenosine - triphosphate), the energy - currency of the cell. Without food, the cyclist would run out of energy and be unable to continue pedaling.

Answer:

The cyclist must be fed because food supplies the energy required for pedaling. Through cellular respiration, the chemical energy in food is converted into ATP, which powers the cyclist's muscles. Without this energy source from food, the cyclist will exhaust their energy reserves and be unable to keep pedaling.
