Identify and analyze species interactions: competition (resource partitioning), predation (functional responses), symbiosis (mutualism, commensalism, parasitism); explain ecological succession (primary/secondary); evaluate biodiversity importance and keystone species effects
Construct food webs and energy pyramids; apply 10% energy transfer rule; calculate ecological efficiency; analyze trophic cascades and bottom-up/top-down control
Trace carbon, nitrogen, water, and phosphorus cycles through biotic and abiotic components; explain human impacts on cycles (fossil fuels, fertilizer use, deforestation); propose mitigation strategies
Analyze biodiversity threats (habitat loss, invasive species, climate change, overexploitation); evaluate conservation strategies (protected areas, restoration, sustainable practices); connect human population growth to resource consumption and environmental impact
