The correct response is: It maintains other populations.
Top predators play a crucial role in ecosystems by helping to regulate the populations of other species, which in turn maintains the balance of the ecosystem.

The biodiversity of the area reaches equilibrium.
The biodiversity of the area reaches equilibrium.
The biodiversity of the area increases.
The correct response is: The biodiversity of the area increases.
Normal seasonal flooding can enhance biodiversity by creating new habitats, replenishing nutrients, and allowing various plant and animal species to thrive.
How is the impact of seasonal flooding different from damming a river?(1 point)
Responses
Seasonal flooding does not impact biodiversity for as long term as damming.
Seasonal flooding does not impact biodiversity for as long term as damming.
Seasonal flooding helps balance biodiversity, but damming does not.
Seasonal flooding helps balance biodiversity, but damming does not.
Seasonal flooding is not considered an ecological disturbance like damming.
Seasonal flooding is not considered an ecological disturbance like damming.
Seasonal flooding decreases biodiversity, but damming does not.
Responses

Seasonal flooding helps balance biodiversity, but damming does not.
Seasonal flooding is not considered an ecological disturbance like damming.
Seasonal flooding is not considered an ecological disturbance like damming.
Seasonal flooding decreases biodiversity, but damming does not.
The correct response is: Seasonal flooding helps balance biodiversity, but damming does not.
Seasonal flooding typically promotes biodiversity and ecological balance by allowing species to thrive in dynamic and changing conditions, while damming can disrupt natural water flow and significantly alter or decrease biodiversity over the long term.
Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?(1 point)
Responses
No, because increases and decreases in average temperatures are normal.
No, because increases and decreases in average temperatures are normal.
Yes, because such a change could have a large-scale impact on wildlife.
Yes, because such a change could have a large-scale impact on wildlife.
Yes, because any slight change in temperature is considered a disruption.
Yes, because any slight change in temperature is considered a disruption.
No, because it would not create large-scale changes in the environment.
Responses
No, because increases and decreases in average temperatures are normal.

Yes, because any slight change in temperature is considered a disruption.
No, because it would not create large-scale changes in the environment.
The correct response is: Yes, because such a change could have a large-scale impact on wildlife.
A long-term increase in average temperatures can significantly affect ecosystems by altering habitats, disrupting food chains, and impacting species' survival and reproduction, leading to potentially large-scale ecological changes.
