What is the difference between a species and a population?
a species includes only one type of organism, while a population includes many types of different organisms.
a species includes only organisms that can reproduce together, while a population includes groups of organisms that cannot all reproduce together.
organisms of the same species must live in similar climates, while organisms of the same population can live in different ecosystems with different climates.
organisms of the same species can live in different areas, while organisms of the same population live in only one area.

What adaptations can prey use to avoid predation

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
