Changes in a population of coyotes are shown in the table below.
Dahasolnce [82]

Answer:

B

Explanation:

The most likely explanation for why the size of the coyote population remained unchanged between 2006 and 2008 would be that <u>the population reached its carrying capacity of the environment.</u>

<em>The carrying capacity of a population of an organism  is the maximum number of the organism the environment can support based on the resources the environment has. Below this number, the population of the organism has the potential to increase while above the carrying capacity, the population has the tendency to decrease. The population of an organism fluctuates around the carrying capacity without any major decrease or increase.</em>

The correct option is B.

<span>When I first read the question, I wasn't so sure about this.  I figured they would probably just wander around for a while, possibly a few months or years, and then die out little by little as they competed for food and fell to predators.  </span>

<span>However, in the meantime they would likely eat everything, and then attract large numbers of predators, who would then have many babies.  </span>
