Biological Productivity - the rate of generation of biomass in an ecosystem; western margins of continents have high prosuctivity and the Artic has the most because of high levels of upwelling and downwelling bc there is no thermocline Photosynthesis formula - 6CO2 + 6H2O + sunlight ---> C6 H12 O6 + 6O2 Photosynthesis - Inputs: Carbon Dioxide, water, sunlightOutputs: Glucose, oxygen Euphotic Zone - Upper layer of a body of water through which sunlight can penetrate and support photos...

"High-grade" energy refers to - chemical, electrical, and mechanical energy A crayfish's daily life consists of swimming, foraging, and escape from predators. Explain how anaerobic and aerobic metabolism interact to help the crayfish live through the day. What is the role of oxygen in these activities? - Burst = anaerobic - dependent upon redox balance, phosphagens, and nutrients Sustained = aerobic - O2 dependent A nonessential amino acid is an amino acid that - can be synthesized by th...
