Dogs vs. Cats in Home More homes have dogs than cats, but more cats than dogs owned -> people own multiple cats Most popular pet Freshwater Fish What country owns most pets // Why? U.S. // More income, more space 3 Fish Classes Agnatha -> jawless fish, parasites Chondrichthyes -> sharks ***Osteichthyes -> bony fish Cell in Fresh Water They expand, so fish drink very little and urinate a lot Cells in Salt Water They shrink, so fish drink a lot and urinate a little ...

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 photosynt...
