3 ) Use mathematics and graphic models to compare factors affecting biodiversity and populations in ecosystems.

[SC2015] ENVS (9-12) 4 :

4 ) Engage in argument from evidence to evaluate how biological or physical changes within ecosystems (e.g., ecological succession, seasonal flooding, volcanic eruptions) affect the number and types of organisms, and that changing conditions may result in a new or altered ecosystem.

[MA2019] PRE-19 (9-12) 7 :

7. Determine numerically, algebraically, and graphically the limits of functions at specific values and at infinity.

a. Apply limits of functions at specific values and at infinity in problems involving convergence and divergence.

[ELA2021] (11) 8 :

8. Read, analyze, and evaluate texts from science, social studies, and other academic disciplines and explain how those disciplines treat domain-specific vocabulary and content and organize information.

They're an important part of the ecosystem. They prevent disease and clean up carrion. Yet, they're also a nuisance to homeowners and a threat to livestock. Their population has recovered and grows at an incredible rate. At what point can we say that there are too many black vultures in America?

This informational material will apply a precalculus concept--limits of functions--to an environmental science issue--how biological and physical changes within an ecosystem can affect the population growth of a species. There are additional links provided for students to explore more about this issue.
