Based on this population growth graph, what can be determined about the population?

the rabbit population grows exponentially.
the rabbit population had many limiting factors in the first ten years.
the birth rate equals the death rate for a majority of the twenty-year period.
the carry capacity is around 0.4 million.

Based on the population growth graph given above, one can determine that THE CARRYING CAPACITY OF THE POPULATION IS AROUND 0.4 MILLION.

In biology, carrying capacity refers to the maximum number of a particular species of plant or animal than an ecosystem can sustain indefinitely given the amount of resources that are available. Resources refer to the requirements that the concerned animal or plant specie need to survive in that environment and these include: food, water, mates, habitats, etc.

Looking the graph giving above, one will notice that, the number of individual in that population continued to increase until a maximum point is reached after which there was a slight decline in the population. The maximum point reached on the graph is the carrying point and the value from the graph is about 0.4 million.
