Question

1. what changes did the researchers observe in the size and growth of the different types of trees and the population of elk during the data collection periods depicted in the graphs? make a claim and support it with specific evidence (numbers) from the graphs. during the period _willow_ to _cottonwood_, elk... at the same time, ... from _ to _, ... during _ it can be observed that _ at the same time that _

Explanation:

Step1: Identify data from graphs

Since no graphs are provided, assume we would look for data - points on tree size, growth rates and elk population numbers at different time - intervals.

Step2: Make claims

For example, if tree size data shows an increase and elk population a decrease in a certain period, claim could be: "As the size of willow trees increased from year X to year Y, the elk population decreased from Z to W."

Step3: Support with evidence

If the graph shows willow tree size increased from 10 cm to 20 cm in 5 years and elk population decreased from 50 to 30 in the same 5 - year period, evidence would be: "Willow tree size grew from 10 cm to 20 cm and elk population dropped from 50 to 30 between the start and end of the 5 - year period."

Answer:

Without the actual graphs, a specific numerical - based answer cannot be provided. But the general approach would be to claim relationships like "When the size of [tree type] increased, the elk population decreased" and support it with data points from the graphs such as "The [tree type] size went from [initial value] to [final value] while the elk population went from [initial number] to [final number] in the period from [start time] to [end time]."
