Step 1

5 watt per kilogram. Therefore, the metabolic rate for the wolf can be calculated by multiplying the specific metabolic rate by the mass of the wolf. This gives us: \[ \text{Metabolic rate for the wolf} = 1.5 \, \text{watt/kg} \times 40 \, \text{kg} = 60 \, Show more…

Key Concepts

Scaling Laws in Biology

Scaling laws in biology describe how various biological quantities change with the size of an organism, often according to a power law. For instance, many physiological rates, such as metabolic rate, scale with body mass raised to a specific exponent. These relationships allow scientists to predict how changes in body mass affect energy consumption, life span, and other biological functions.

Allometric Scaling

Allometric scaling refers to the study of the relationship between the size of an organism and its shape, physiology, and behavior. In biological contexts, it is used to understand how different properties, like metabolic rate or energy usage, change non-linearly with body mass. This concept is crucial in comparing different species and in predicting how energy demands vary with size according to a specific scaling exponent.
