Step 1
Describe how the body temperature of the iguana affects its oxygen consumption.
Answer
As the body temperature of the iguana rises, there is an increase in the rate of biochemical reactions within the body. This is due to the influence of temperature on chemical and metabolic processes. Higher temperatures enhance enzyme activity, leading to more respiration occurring. More respiration demands more oxygen, which results in increased oxygen consumption as observed in the data.
