Ch. 1 &2 Study Guide Concepts □ I can explain the one-way flow of energy through the biosphere and how stored biological energy in the biosphere is eventually “lost” as thermal energy □ I can explain how biological energy in the biosphere can be perceived as a balance between both photosynthetic and chemosynthetic, and cellular respiratory activities □ I can explain the structure of ecosystem trophic levels, using models such as food chains and food webs □ I can explain quantitatively, energy exchange in ecosystems, using models such as pyramids of energy , biomass, and numbers □ I can explain the interrelationship of energy, matter and ecosystem productivity (biomass production) □ I can explain how the equilibrium between gas exchanges in photosynthesis and cellular respiration influences atmospheric composition Vocabulary Dynamic Equilibrium Biosphere Biotic Abiotic Population Community Ecosystem Biodiversity Food Chain Producer Consumer Indicator Species Herbivore Carnivore Omnivore Detritus Decomposer Habitat Uv Radiation Ozone Trophic Level Autotroph Primary Consumer Secondary Consumer Heterotroph Food Web Chemosynthesis Chemoautotroph Thermodynamics Ecological Pyramid Monoculture
