Endangered Species

Share multiple examples of endangered species, including why the species face extinction.; describe attempts being made to study and/or preserve endangered species; and provide characteristics of birds commonly called “raptors” and explain why these species are often at risk for extinction.


Managing Species

Indicate the characteristics of “pest” animals and describe the impacts they have on humans and human products; provide examples of invasive species, including how they have moved and the impacts they have on endemic species; and explain the technological steps being taken to revive extinct species from genetic samples.


Coevolution

Define coevolution and give examples of species that are impacting each other over time, including origins of eukaryotes; provide examples of symbiosis, including parasitism, mutualism, and commensalism; and summarize the structural characteristics, representative organisms, and ecosystem significance of cnidarian species.
