Question
Which of the following would be an example of ecological balance?
- A predatory bat species that do not have a nesting habitat
- A predatory bat species that help keep mosquito populations in check
- A bat species that migrates to a new ecosystem
- An individual bat that does not survive because of winter conditions
Hint:
In a balanced ecosystem, an interdependence of each factor exists.
The correct answer is: A predatory bat species that help keep mosquito populations in check
A predatory bat species that does not have a nesting habitat will not be able to reproduce. Hence, this is not a balanced ecosystem.
A predatory bat species that help keep mosquito populations in check is a balanced ecosystem.
A bat species that migrates to a new ecosystem is not a balanced ecosystem.
An individual bat that does not survive because of winter conditions is not a balanced ecosystem.
Hence, (B) is the correct answer.
