What is primary succession?
The gradual reintroduction of communities in lifeless areas where there is no soil
The gradual change in communities in an area that has been disturbed
The quick process of evolution of an ecosystem over time
The maximum population that a habitat can sustain
What is the difference between primary and secondary succession?
Primary succession takes longer to rebuild than secondary succession
Primary succession occurs in areas with soil, while secondary succession occurs in areas without soil
Primary succession occurs in areas that have been disturbed, while secondary succession occurs in lifeless areas
Primary succession is quicker to rebuild than secondary succession

Exponential
Logistic
Both
Neither
What are limiting factors in population growth?
Food
Water
Space
All of these are limiting factors in population growth
What is carrying capacity?
The maximum population that a habitat can sustain
The number of individuals in a given geographic area
The gradual change in communities in an area that has been disturbed
The process of evolution of an ecosystem over time

Density-dependent
Density-independent
Both
Neither
What happens when a population overshoots the carrying capacity?
Dieback or population crash
Continue to grow
There is no such thing as carrying capacity
All of these are correct

Long life spans, few large offspring, extensive parental care
Short life spans, few large offspring, extensive parental care
Long life spans, many small offspring, little parental care
