Question
What are the potential effects on an ecosystem if the population of a predator species decreases significantly?
Answer
If the population of a predator species decreases significantly, the population of its prey may increase rapidly. This can lead to overgrazing or overconsumption of vegetation, which may disrupt the balance of the ecosystem and negatively affect other species that rely on those plants for food and habitat.
Explanation
This question tests the understanding of interrelationships within an ecosystem and how changes in one component can affect others. It requires students to apply their knowledge of ecosystem dynamics.
Common mistake
Misunderstanding Ecosystem Components
Students often think that changing one component of an ecosystem only affects that component without considering the interconnectedness of all components.
To fix this, students should study examples of how altering one factor, such as the removal of a predator, can lead to changes in population sizes of other species and overall ecosystem balance.
