13
1
What kind of population growth occurs when resources are limited?
14
1
What kind of limit to population growth would competition within the population be considered?
15
1
What type of limit to population growth would a natural disaster be?
16
1
In a population growth curve, what type of growth is seen with the rapid increase population, creating a steep curve?
17
1
In a population growth curve, what type of growth has been reached when the curve levels off?
18
1
Which limit to population growth is the maximum population size that the environment can support?
19
1
Which ecological relationship will limit growth in a population if more than one species relies on the same resources, like land and food, as another?
20
1
What is the ecological relationship between the wolves and the elk in the example?
21
1
When predator and prey populations exist in the same ecosystem, the population growth of both species will_____ over time.
22
1
What kind of limiting factor of population growth would predation be?
23
1
What molecule are human producing on a massive level that is causing global temperatures to rise?
24
1
In the food chain example, of whitebark pine, squirrels, and grizzly bears, which represents the primary producer?
25
1
Since the Whitebark pine only grows in cooler climate elevations, what will happen to the habitat as the global climate warms?
26
1
If climate change decreases the habitat of the Whitebark pine, what will likely happen to the consumers that rely on the pine?
