Population Dynamics and Ecological Succession

Nesting birds often space themselves evenly from other nests. This pattern is called

• clumped dispersion.
• uniform dispersion.
• random dispersion
• scatter dispersion

Which of the following will increase the size of a population?

• emigration and births
• immigration and deaths
• immigration and births
• emigration and deaths

What type of growth is shown on this graph?

• logistic (S-Curve)

• exponential (J-Curve)

• Linear

• density-independent

Which of the following is a density-independent limiting factor?

• natural disaster
• predation
• disease
• parasitism

The way in which individuals of a population are spread out is called

• population density
• survivorship
• population dispersion
• logistic curve

What type of population growth is shown in the graph?  

• logistic growth
• logical growth
• exponential growth
• density-dependent growth

Estimate the carrying capacity.

• 100 deer

• 80 deer

• 60 deer

Predator population lags behind prey population because......

• Increase in predators leads to decrease in prey

• Increase in predators leads to increase in prey

• Increase in predators leads to decrease in producers

• Increase in producers leads to increase in prey
