Age Structure Diagrams with a Broad Base Suggest

Question

Age structure diagrams with a broad base suggest:
A)Environmental resistance is not at work
B)The biotic potential must be larger than usual
C)The individuals must be larger than usual
D)The population will continue to grow for some time
E)The population is shrinking

Accepted Answer

When the prereproductive group is the largest of the three groups,the birthrate is higher than the death rate,and a pyramid-shaped diagram is expected.Under such conditions,even if the growth for that year were matched by the deaths for that year,the population would continue to grow in subsequent years.
