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 number of wolves on y - axis from 25 to 175 and year on x - axis from 1996 to 2023, 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 trend

Check the graph from 1996 to 2004. The number of wolves increases (from ~25 to ~175), so positive growth holds.

Step2: Analyze 2006 - 2008 trend

From 2006 (low ~120) to 2008 (high ~175), the population rises, so this statement is supported.

Step3: Analyze carrying capacity post - 2009

Post - 2009, the population fluctuates around 100 (e.g., 2011: ~98, 2014: ~85, 2017: ~110, but generally hovers near 100), so carrying capacity ~100 is supported.

Answer:

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.
