3. What is this type of population growth called?
a) exponential
b) continuous
c) logistic
d) linear
e) discrete







































































































You said that this graph represents

(b) continuous population growth.
no -- in the context of population dynamics, "continuous" describes whether reproduction occurs year-round, rather than describing a form of population growth. try again.

You said that this graph represents(c) logistic growth.

no -- "logistic" growth is growth in which the population starts small, increases gradually at first, then increases more rapidly, but then the growth rate slows down and eventually population size stabilizes at a carrying capacity.

You said that this graph represents (d) a linear relationship.

no -- a "linear" relationship is a "straight-line" relationship between two variables. A linear increase in population size through time probably never occurs in nature.

You said that this graph represents

(e) discrete growth.
no -- "discrete" is a term that refers to the time pattern of reproduction (the opposite of "continuous", meaning "occurring only during certain times of year"), not to the pattern of population growth. Click here to return to question 3.
