This study guide covers energy flow in ecosystems, starting with the sun as the primary source. It explains trophic levels (autotrophs and heterotrophs), energy loss as heat, and net gain/loss in organisms. It also discusses endotherms vs. ectotherms, metabolic rates, and r/K reproductive strategies. Finally, it explores ecosystem disruptions from changes in energy resources and provides practice questions and exam tips.
