Understanding Population Growth Models

A few plant-eating salamanders manage to float on a log to a large island in the Pacific that did not have any other salamander species previously. The salamanders find the island has abundant plants for food and no predators. On average, a salamander has four offspring per year and lives for one year.

1) How will the population of salamanders change over the first few years?

a) The population will increase steadily by a constant amount each year.

b) The population will increase more rapidly each year than the year before.

c) The population will increase steadily for a few years and then decrease steadily back to 0.

d) The growth in the first few years depends on the size of the island.
