Document Summary
In multiple choice format, identify : difference between ecology and environmental activism. Adaptation: a characteristic that improves survival or reproduction. Natural selection: individuals with certain adaptations tend to survive and reproduce at a higher rate than other individuals: whether an example given is an adaptation or an example of natural selection, the driving force(s) of evolution. Organism pop"n community ecosystem biosphere: why an ecosystem isn"t just a collection of populations, the correct definitions of population, community, ecosystem, landscape, and biosphere . Population: group of individ of a species living & interacting in a particular area. Community: association of populations of different species in the same area. Ecosystem: community of organisms + the physical environment. Landscapes: areas with substantial diff, typically incl multiple ecosystems. Biosphere: all living organisms on earth + the environments in which they live: how npp relates to producers in an ecosystem. **the process is iterative and self-correcting: reasons why amphibians in particular are experiencing population declines.
