Predict Interaction Outcomes Practice Test

Refer to the ecosystem model: In a grassland, rabbits (herbivores) eat grass (producers), and hawks (predators) hunt rabbits. During a 6-week drought, rainfall stays very low and grass growth slows. Field notes show rabbit sightings decreasing each week, and hawks are observed hunting longer each day. Interaction outcomes can be predicted using evidence. Which outcome is most likely for the hawk–rabbit interaction during the drought, based on the evidence and conditions?

Refer to the ecosystem model: In a freshwater pond, algae (producers) are eaten by zooplankton (herbivores), and small fish (predators) eat zooplankton. After a week of warm, sunny weather, algae coverage increases. A survey shows zooplankton density rises 3 days later, followed by a slight increase in small fish feeding activity. Interaction outcomes can be predicted using evidence. Which prediction about the fish–zooplankton interaction is supported by the evidence under these conditions?
