What happens to prey density when predator density is high?1 pointIt is constantIt stays the sameIt increasesIt decreaases

Analysis of the Question

Understanding the dynamics between predator and prey is crucial in ecology. Typically, an increase in predator density leads to more significant predation pressure on prey populations.

Relevant Concepts

1. Predator-Prey Dynamics: The relationship between predators and their prey can be described by various ecological models, such as the Lotka-Volterra equations.
2. Impact of Predation: When the number of predators increases, they consume more prey, which generally leads to a decrease in prey density.

Conclusion

Considering the relationship outlined, when predator density is high, the prey density is likely to decrease as predators have more opportunity to hunt and consume prey.

Final Answer

• It decreases.
