Answer: It is a partial regulator using behaviour to manage body temperature.
- A It is a regulator maintaining constant temperature metabolically
- B It is migrating to a new habitat permanently
- C It is a partial regulator using behaviour to manage body temperature
- D It is entering diapause to survive heat
Correct answer: C. It is a partial regulator using behaviour to manage body temperature
Explanation: Lacking internal thermoregulation, the lizard uses behavioural means, basking to warm up and moving to shade to cool, a partial form of regulation.
Exponential growth produces an ever-steepening J-curve with no limit, an unrealistic long-term model; logistic growth produces an S-curve that levels off at the carrying capacity K, as growth rate (K−N)/K shrinks to zero once resources are fully used.
Concept context
How organisms interact with abiotic factors and respond to stress, plus population attributes, growth models, and interspecific interactions such as predation, competition, and mutualism.
