Question

this graph shows how the population of bison in a section of present - day yellowstone national park has changed over time since 1860.
what is the approximate carrying capacity for bison in this section of the park?
150
275
350
450

Explanation:

Carrying capacity is the maximum population size of a species that an environment can sustain. In a population - vs - time graph, it is represented by the upper limit of the population size when the population levels off. Looking at the graph, the population of bison seems to level off around 350.

Answer:

350
