12. The graphs below illustrate 3 different populations. Graph
1 represents a population of fish introduced into a lake. Graph 2 represents
the world's human population. Graph 3 represents a population of paramecia (a
type of "wee beastie") in a laboratory dish. Study the graphs and
then answer the question below.
Because there is no dashed line in graph
2, this means that the carrying capacity for the human population has not yet
been reached. This means the human population will keep increasing.
