Which of the following statements regarding species interactions is true? The herbivore-food resource relationship observed in many terrestrial systems is not observed in aquatic systems as a result of the stability of temperatures in aquatic habitats. Most zooplankton and phytoplankton (the food source for zooplankton) show correlated blooms in population in response to global warming. Plant growing season (time of breaking dormancy and length of growing season) is highly correlated with day length. Successful reproduction of many herbivore species depends on the timing of births being closely correlated with vegetation growth beginning at roughly the same time. Many animal mating rituals are triggered by changes in temperature. .
