Why is a runner a heterotroph?

Answer 1

A runner is considered a heterotroph because it cannot produce its own food and instead relies on consuming organic substances for energy and nutrients. Heterotrophs, including humans and many animals, obtain their sustenance by eating plants, other animals, or organic matter. In the case of a runner, their body metabolizes the carbohydrates, proteins, and fats derived from the food they eat to fuel their physical activity. This process is essential for maintaining energy levels and supporting bodily functions during exercise.
