Question

The graph represents a typical carrying capacity graph, or the maximum population size a certain environment can support for an extended period of time, for particular species. Under ideal conditions, a population naturally increases until it overshoots the carrying capacity. At this point, the environment can no longer provide for the species, due to a number of different environmental resistances. The population, due to lack of resources, will begin to die out, allowing the environment to recover.
Based on the trends of the carrying capacity graph, what is the predicted population of organisms, in millions, in 1950?
A) 1.25 million
B) 1.75 million
C) 2.0 million
D) 3.0 million

Answer 1

Answer:

B) 1.75 million

Explanation:

In the graph, the blue line is labelled as the carrying capacity. This must mean the purple line is the predicted population.

Above "1950" on the x-axis, the purple line reaches a space about halfway between 1.5 million and 2.0 million.

1.75 million is halfway between these two numbers.
