The majority of animals and nearly all plants cannot maintain a constant internal environment and change with the surroundings; such organisms are called:

Answer: Conformers.

  • A Regulators
  • B Migrators
  • C Partial regulators
  • D Conformers

Correct answer: D. Conformers

Explanation: Most species are conformers whose internal body temperature and osmotic concentration change with the ambient environment, unlike the few regulators.

Exponential (J-curve) vs Logistic (S-curve) GrowthtimePopulation (N)Exponential (unlimited resources)K (carrying capacity)Logistic (limited resources)Logistic growth slows as N approaches K; exponential growth never slows down

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.
