- A A defect caused by the host
- B A temporary dormancy response
- C Evidence of a beneficial mutualism with the host

Correct answer: D. A parasitic adaptation as the host gives digested food

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.
