The following graph is representative of what type of population growth?

a.
logistic
b.
exponential
c.
linear
d.
triangular

Option a. Logistic

Explanation:

We will analyze every option one by one

a. Logistic graph

Logistic graph is a typical S-shaped graph showing three curves.

Starting curve shows a less growth because less number of species.

Then a steep curve showing fast growth because of good number of species then curve showing less growth because of limited resources in the environment.

This option is the correct option.

b. Exponential graph

Exponential graph shows a steep growth in its curve so this option doesn't match the graph.

c. Linear graph

Linear graph shows a straight line so this option is not correct.

d. Triangular

Triangular graph is a three dimensional graph having three vertices. So this option is again not correct.

Therefore Option a. Logistic graph is the correct one.
