D. See 4 graphs on page 2 – Elk Population and the 3 graphs of Cottonwood, Willow, and Aspen Trees. Use information from the 4 graphs to describe the changes in the (1) size and growth of the trees, and (2) the population of elk from 1995 to 2010.
From the 4 graphs on page 2, we can observe the following changes in the size and growth of the trees:
1) Cottonwood Trees: The graph shows that the number of cottonwood trees was relatively stable from 1995 to 2000, with a small decrease in numbers. However, from 2000 to 2005, there was a significant decrease in the population of cottonwood trees. This decline continued, although at a slower rate, from 2005 to 2010.
2) Willow Trees: The graph indicates that the population of willow trees experienced a steady decline from 1995 to 2000. This decline continued at a similar rate from 2000 to 2005, and the population remained relatively stable from 2005 to 2010.
3) Aspen Trees: The graph displays a steady increase in the population of aspen trees from 1995 to 2000. However, this growth slowed down significantly from 2000 to 2005, and the population remained relatively stable from 2005 to 2010.
Regarding the elk population, the information from the 4 graphs shows the following changes:
The graph of elk population displays a gradual increase in numbers from 1995 to 2000. This growth continued at a slower rate from 2000 to 2005, and the population remained relatively stable from 2005 to 2010.
Overall, from 1995 to 2010, the number of cottonwood trees decreased, while the population of willow trees remained relatively stable. Aspen trees showed an initial growth, followed by a slowdown in growth. The elk population experienced a gradual increase during this time period.
