APFIVE Life History Strategies in Variable Environments
Researchers conducted an experiment on a biennial plant species by varying soil nutrient levels for different populations over several growing seasons. Which of the following results provides the strongest evidence that life-history strategies are adaptations for optimizing energy allocation in variable environments?
A
Plants in nutrient-rich conditions exhibited reduced photosynthetic efficiency
B
Plants in fluctuating nutrient conditions showed delayed flowering until after nutrient-rich periods
C
Plants in nutrient-poor conditions showed increased rates of herbivory
D
Plants in all conditions maintained constant biomass regardless of nutrient availability
