Drought and Predator-Prey Dynamics

A prolonged drought has affected a grassland ecosystem, significantly reducing the water availability for plants. The primary producers, such as grasses and small shrubs, have become scarce, affecting the populations of primary consumers like rabbits. This scarcity of food has had a cascading effect on the secondary consumers, such as foxes, that rely on these herbivores as their main food source.

In CER format, describe how the drought (an abiotic factor) has altered the predator-prey dynamics in the grassland ecosystem, focusing on the rabbit and fox populations.
