Question

this graph shows the beginning-of-year population counts for wolves in yellowstone national park from 1996 to 2023. yellowstone national park wolf population (graph with year on x - axis from 1996 to 2023 and number of wolves on y - axis from 25 to 175) data source: nps select all the statements about the wolf population that are supported by the graph. the wolf population showed positive growth from 1996 to 2004. the wolf population size increased between 2006 and 2008. the carrying capacity for wolves in yellowstone national park after 2009 was likely about 100 individuals.

Explanation:

Step1: Analyze 1996 - 2004 growth

Check the graph from 1996 to 2004 (approximating 2004 near 2005). The number of wolves rises from ~25 to ~175, so positive growth. This statement is supported.

Step2: Analyze 2006 - 2008 growth

From 2006 (after 2005's dip) to 2008, the graph shows an upward trend (from ~120 to ~170), so population increased. This statement is supported.

Step3: Analyze post - 2009 carrying capacity

After 2009, the population fluctuates around 100? No, it has values above and below 100 (e.g., 2010 ~95, 2017 ~110, 2020 ~80, 2023 ~110). Carrying capacity is a stable limit, but here it's fluctuating, so this statement is not supported.

Answer:

The wolf population showed positive growth from 1996 to 2004.
The wolf population size increased between 2006 and 2008.
