After 1967, the elk population began to surge. Approximately how long after the extermination of the wolves did it take to reach this point? Your answer should be estimated to within ± 1 year.
Assume the carrying capacity of elk in this ecosystem is just below 20,000 individuals. Based on the graph above, name one (1) biotic and one (1) abiotic factor and explain how each factor has directly impacted the elk population. Use the matching options below to answer the questions.
Based on the elk population data from approximately 1967 to 1987, what effect do you think the elk population had on the populations of producers?
What do we call species like wolves who have a greater than normal impact on other species, whether the effects are direct or indirect?
How do the data points from 2005 specifically illustrate the relationship between elk and wolves?
Of the prey species included in the graphs, what is the wolves’ preferred prey?
Using quantitative data from the graphs as evidence, choose the effect the reintroduction of wolves has on the carrying capacity of Elk
Using quantitative data from the graphs as evidence, choose the effect the reintroduction of wolves has on the carrying capacity of Bison
Using quantitative data from the graphs as evidence, choose the effect the reintroduction of wolves has on the carrying capacity of Beavers

Explain how the presence of wolves supports ecosystem homeostasis.
From what do elk obtain the chlorophyll and nitrogen found in their waste?
According to the graph, what abiotic factor seems to impact the amount of chlorophyll and nitrogen in the elk’s waste?
Choose the claim that states why the consumption of chlorophyll and nitrogen by elk increases when they do.

Of what macromolecule does the wolf diet primarily consist?
What are the building blocks of this macromolecule?

What is a general rule that can be applied to estimate the percentage of energy typically transferred from level to level?
Based on the DNA sequences, which populations are more related? Bubble in TWO choices:
Using both the geographic and genetics data provided, explain how you defined the relationships between the wolf populations above.
How did the population change over time? Describe the trend for each phenotype in the population using evidence from the data.
State a claim as to why the more common color phenotype may be more successful in their habitat.
If you decided to test your claim, what other type of evidence would you collect to support or refute your claim?
