Ecosystems

Key words- Chapter 3 ECOSYSTEMS -solar radiation and heat may be limited at the South Pole in winter -water in limited supply in a desert. -all regimen webs compute on photosynthesis by green plants to provide the sign force store. -productivity is greater in low latitudes-> temperatures argon spunky -> sunlight input is laid- gage } => ideal for photosynthesis -> rush is high -towards the poles-> the rate at which plants jackpot photosynthesis is low => GPP (gross aboriginal productivity) and NPP (net primary productivity) are lower -Whittaker, an American ecologis, branch plotted biomes once against temperature and precipitation THE TRICELLULAR MODEL OF ATMOSPHERIC CIRCULATION -the equator receives most insolation (solar radiation) -> this heats up the breed which raises - as it raises, it cools and the water vapour in the air condenses as rain=> causes: -> the afternoon thunderstorms -> low pressure areas of the equatorial ra inforests - much(prenominal) energy in this air-> continues to rise until is pushed away from the equator to jointure and federation -it cools and then sinks => this air is dry, this is where the desert biome lies.

- the air that dazes towards the equator completes a cellular phoneular telephone to end up where it started=> this movement = “trade annuls”(always blow towards the equator) -at the equator, the north-central and the south trade winds converge and rise again at the inter-tropical convergence zone-> here is the area of little wind=> the cell is called Hadley cell -Westerlies= air t hat blows to higher latitudes at 30°N an! d S -> they wrap up water vapour from the oceans as they blow towards the poles. - Ferrel cell-> the air continues to flow, near to the poles and some back towards the equator. -Coriolis force = the trade winds, westerlies and other winds are deflected to east or west.
