A bird population lives in a habitat where the number of nesting sites is a limiting factor in population growth. In which of the following cases would you expect that the growth of this bird population over the next few generations could be reasonably well approximated by exponential growth? (a) All nesting sites are occupied. (b) The bird population just invaded the habitat, and the population size is still much smaller than the available nesting sites. (c) In the previous year, a hurricane killed more than 90% of the birds in this habitat.

Pollen records show that the number of Scotch pine () grew exponentially for about 500 years after colonization of the Norfolk region of Great Britain about 9500 years ago. Can you find a possible explanation for this growth?

Exponential growth generally occurs when population growth is density independent. List conditions under which a population might stop growing exponentially.
