Why would habitat fragmentation sometimes be more detrimental to species survival than simple loss in habitat area?
a. Threats, such as predators and disease, cannot enter the habitat easily from the outside. b. Local population extinctions can be more easily rescued by other nearby populations. c. Populations can migrate more easily in response to climate change. d. None of the above. 5. True/False: As long as we preserve scattered small natural areas within urban and suburban settings, species will be able to survive. 6. True/False: A small frog becomes extinct in a local state park, but other frogs are able to fill its role in the ecosystem. This species was a keystone species. 7. In Northern Minnesota forests, both fir trees and birch trees need the same resources to survive: access to light, water, and nutrients. They are often found growing next to one another, where birch trees may shade out the firs, but the fir trees are better able to gather nutrients and water than the birches. This is an example of what ecological relationship? a. Mutualism b. Predation c. Competition d. Smack-down 8. Wh
