    • Describe the levels of ecological organization (i.e. organisms, population, community, ecosystem, biome, and biosphere)
    • Describe characteristic biotic and abiotic components of aquatic and terrestrial ecosystems
    • Describe how energy flows through an ecosystem (e.g. food chains, food webs, energy pyramids)
    • Describe biotic interactions in an ecosystem (e.g. competition, predation, symbiosis)
    • Describe how matter recycles through an ecosystem (i.e. water cycle, carbon cycle, oxygen cycle, and nitrogen cycle)
    • Describe how ecosystems change in response to natural and human disturbances (e.g. climate change, introduction of nonnative species, pollution, fires)
    • Describe the effects of limiting factors on population dynamics and potential species extinction
