BIOL 230 Lecture Notes - Lecture 1: Effect Size, Calcification, Species Richness
Document Summary
Deeper in water- cooler- therefore can store more co2 there. Currents moving because of temperature differences: there is wind- because of temperature differential. Temperature differential- the pump the moves water: greenland- melting, then cold fresh water- go into pump/ north water. Co2 dissolved into plants in the water. Organisms eating the plants/ other- respire- then release co2. If lower part of see- will not have the use of co2 from bottom for a long time. Biomass/ unit area/ unit time= rate of change productivity: on x axis- mg/m/ yr. More production above 0, less production below 0: blue is more to the left- greater decline in productivity. Change in pool= big change: d) reduced plant biomass. Looking at trophic levels: correct- e) increase in terrestrial primary productivity through co2 fertilization- increase npp counters climate change. A feedback loop- more primary productivity- then can regulate world itself- when increase in co2.
