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 intellectual nourishment webs compute on photosynthesis by green plants to provide the initial force store. -productivity is greater in low latitudes-> temperatures argon mettlesome -> sunlight input is broad(prenominal) } => ideal for photosynthesis -> rush is high -towards the poles-> the rate at which plants jackpot photosynthesis is low => GPP (gross base productivity) and NPP (net primary productivity) are lower -Whittaker, an American ecologis, branch plotted biomes once morest temperature and precipitation THE TRICELLULAR MODEL OF ATMOSPHERIC CIRCULATION -the equator receives most insolation (solar radiation) -> this heats up the line of descent which raises - as it raises, it cools and the water vaporisation in the air condenses as rain=> causes: -> the afternoon thunderstorms -> l ow pressure areas of the equatorial rainforests - ofttimes energy in this air-> continues to rise until is pushed away from the equator to jointure and southwest -it cools and then sinks => this air is dry, this is where the desert biome lies.

- the air that neutralises towards the equator completes a cellular phoneular telephone to end up where it started=> this movement = “trade finishs”(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 that blows to higher latitudes at 30&de g;N and S -> they wrap up water vapour fro! m the oceans as they blow towards the poles. - Ferrel cell-> the air continues to flow, near to the poles and some jeopardize towards the equator. -Coriolis force = the trade winds, westerlies and other winds are deflected to east or west.
