Population Dynamics Eoc

To measure population density, you must divide the number of individuals living in a defined space by the

• area of the space
• birth and death rates
• carrying capacity
• height of the space

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
