What would be the growth rate (r) of an island population of 1000 that has 30 births per 100 population, 20 death per 100 population, 5 immigrants per 100 population, and 10 emigrants per 100 population?
+50
Based on the accompanying figure, which of the following age intervals has the highest death rate?
0-1
Refer to the accompanying figure. A population that produces a large number of offspring, but the offspring must survive independently, would be represented by the curve labeled:
A
Refer to the accompanying figure. At which point on the graph is the population increasing exponentially?
B
On the accompanying figure, identify the point that indicates the carrying capacity for this population.
D
