- A Diapause is said to result in the permanent death of the organism, making it functionally identical to ordinary mortality in every way according to conventional understanding
- B Diapause is a reversible, suspended developmental state allowing the organism to resume normal development once favourable conditions return, unlike mortality which is irreversible
- C Diapause is sometimes described as a phenomenon that occurs mainly within plant seeds, and rarely within zooplankton, in routine practice under typical conditions
- D There is reported to be essentially no meaningful functional difference between diapause and outright mortality, according to standard textbooks in general practice
Correct answer: B. Diapause is a reversible, suspended developmental state allowing the organism to resume normal development once favourable conditions return, unlike mortality which is irreversible
Explanation: Diapause is a temporary, reversible suspension of development that helps the organism survive unfavourable periods; once conditions improve, the organism resumes its normal life cycle, unlike mortality which is a permanent loss of the individual from the population.
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.
