Predator-Prey Relationships Quiz

A predator-prey relationship is an important way that we can look at the interrelationship between different organisms. It refers to the relationship between an organism (predator) that hunts and consumes another organism (prey).

The role of the predator in a predator-prey relationship is to hunt and consume the prey organism.

The prey population increases when the conditions are right, such as when there is plenty of food and the predator level is low. This allows for increased reproduction.

<p>The prey population peaks and starts to drop down when there is an increased number of predators and less food available for the prey. This leads to a decrease in reproduction and an increase in predation.</p> Signup and view all the answers

<p>The predator population peaks and then drops down when there is a decrease in prey population due to reduced food availability. This leads to a decrease in predation and a decrease in reproduction for the predators.</p> Signup and view all the answers

<p>Some key observations about the predator-prey relationship are: 1) Both populations have the same pattern of peaks and troughs. 2) There are more prey organisms than predators, which is due to the inefficiency of energy transfer through the food chain. 3) The predator graph is delayed behind the prey graph.</p> Signup and view all the answers

<p>The prey and predator populations are interrelated in that changes in one population can lead to changes in the other population. For example, an increase in prey population can lead to an increase in predator population, and a decrease in prey population can lead to a decrease in predator population.</p> Signup and view all the answers

<p>Human activities can impact the predator-prey relationship. If humans impact one population, it can have an impact on the other population as well. For example, overhunting of predators can lead to an increase in prey population, while habitat destruction can lead to a decrease in both predator and prey populations.</p> Signup and view all the answers
