Provide an example of how a new pathogen could influence the interactions between species in a community.

For example, if a new pathogen affects a population of frogs, their decline could lead to an increase in the population of insects that frogs typically prey on. This change can disrupt the food web, as the increase in insects may lead to more competition for food among other insectivorous animals.

This answer is effective as it illustrates a specific scenario showing the cascading effects of a pathogen on species interactions within a community. The question assesses the student's ability to apply their knowledge of biotic factors to real-world examples.
