Question

1. figure 1 shows the population sizes for the moose population and the wolf population on isle royale. based on the data in figure 1, which of the following is the best estimate of the carrying capacity of the moose population? population of wolves and moose on isle royale, 1960 - 2005 0 1955 1965 1975 1985 1995 2005 year 30 50 1,500 2,500

Explanation:

Step1: Understand carrying - capacity concept

Carrying capacity is the maximum population size of a species that the environment can sustain indefinitely. In a population - vs - time graph, it can be estimated by looking at the long - term average or the upper limit that the population tends to stabilize around.

Step2: Analyze the moose population graph

Looking at the moose population (dashed line) over the years from 1955 - 2005, the population fluctuates but seems to stabilize around 1500. It has periods where it goes above and below this value, but this is the value around which the long - term average seems to lie.

Answer:

1,500
