[Campbell Biology P.815] Which statement accurately distinguishes between annuals, biennials... | Practice Question
Which statement accurately distinguishes between annuals, biennials, and perennials based on their life cycles?
A: Annuals die after producing seeds and fruits, typically within a single year or less, to maximize energy transfer to reproduction.
B: Biennials complete their entire life cycle, including seed production, within one growing season, similar to annuals.
C: Perennials live many years but produce seeds only in their first year, then focus on vegetative growth.
D: All annuals are staple food crops, while biennials and perennials are never used for food.
Explanation
Annuals complete their entire life cycle—from germination to flowering to seed production to death—in a single year or less. This strategy allows them to maximize the transfer of energy to reproduction.
