When a wolf eats a rabbit a some of the calories contained in the rabbit are converted to free energy and some of the calories are converted to heat. b all of the calories contained in a rabbit are converted to free energy for the wolf. c calories are created that allow the wolf to do work. d some of the calories contained in the rabbit are destroyed.

a. some of the calories contained in the rabbit are converted to free energy and some of the calories are converted to heat.

Explanation:

Energy can be defined as the ability (capacity) to do work.

Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.

This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.

Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.

When a wolf eats a rabbit, some of the calories contained in the rabbit are converted to free energy and some of the calories are converted to heat.
