- 1Energy flowBegins from the sunlight and covering this into photosynthesis establishing the nutrient flow as they are autotrophs
- 2Ecotonehas greater diversity than surrounding ecosystems
- 3tropic levelsQuartenary consumer
Tertiary consumer
secondary consumer
primary consumer
producer
sun - 4polarpermanent ice cap
no plant growth and no animal life away from the coast
e.g. north pole - 5Tundracovered with ice or snow for much of the year,treeless,mostly in the northern hemisphere
e.g arctic tundra - 6Northern coniferous forestlong winter with tick cover of now dominated by conifer tree
- 7Temperate Grasslanderratic rainfalls common fires
- 8heterotrophsconsumes other organisms for their food and nutrients
- 9Autotrophscreates their own food from light (photosynthesis)
- 10Bioaccumulationis the present ecosystem when a non-biodegradable toxic substance is released into the environment.
- 11The carbon cycleDuring photosynthesis plants combine carbon dioxide from the air and hydrogen from water to make carbohydrates.When that plant is eaten the class of the animal breaks down the plants tissue in digestion.
- 12The nitrogen cycle - Fixationis the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium.
- 13The nitrogen cycle - NitrificationThis is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb.
- 14The nitrogen cycle - AssimilationThis is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll.
- 15The nitrogen cycle - AmmonificationThis is part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
- 16The nitrogen cycle - DenitrificationExtra nitrogen in the soil gets put back out into the air. There are special bacteria that perform this task as well.
- 17The phosphorus cycleSediments that are rich in chemical accumulate on the bottom of the sea floor.Currents stir up and provide it to phytoplankton this excess is compacted and over an amount of transformed into rock.
- 18The phosphorus cycle - Human interactionsewage plant
land clearing excess run off - 19Vulnerabilityecosystems that become human induces or natural stress.e.g disruption of natural food web,energy and nutrient flow interference of biophysical components
- 20ResilienceEco system is able to bounce back and adapt back from changes within the environment
- 21BiodiversityGenetic species and ecosystem.The more diverse the diverse the biodiversity the more likely the ecosystem is resilient
- 22extent of ecosystemThe size of any particular ecosystem and the productivity of the ecosystem the more resilient
- 23Locationit affects the plant and snail living in the ecosystem as they may be niche
( specialised within a certain area) - 24Linkageinterdependent related to the species diversity of the ecosystem and the way they function.The created the level of diversity the may be more likely and easily adapt to change.
- 25conserving the ecosystem geneticAllow for the ecological succession and a greater chance of revegetation.
- 26conserving the ecosystem Utilityresources and function that the ecosystem processes
- 27conserving the ecosystem heritageincludes the past users and indigenous owners
- 28conserving the ecosystem intrinsicthe aesthetic value of the ecosystem
- 29isobarslines on the synoptic chart are called isobars.They join together places equal air pressure
- 30Air pressurebarometric pressure is the weight of air pressing down down on the earth.
- 31high pressure cell- anti- cyclone
- winds are blown in a anti - clockwise direction
- isobars increase as you enter in the centre. - 32low pressure cell- cyclone
- clockwise direction
- decreases down the centre - 33troughA trough appears when a region of lower pressures appear in the air circulation around a high pressure cell.
- 34RidgeWhen air from a high pressure cell pushes into a region of lower pressure.
- 35wind speed and directionwinds are named in the direction their are blown
A southerly blow form the south
winds are the strongest when the isobars are closer together - 36warm frontwarm are advances towards cooler air and forces are to rise over,heavier slower and cooler air
- 37cold frontcold are advances into warm air,forcing the lights warm air to rise rapidly clouds form,wind speed increases.
- 38air massis the large parcel of air which relatively uniform temperature and moisture characteristics
- 39atmospherea blanket surrounding the earth.
- 40hydrospherethe interconnecting system of water storage in the atmosphere and lithosphere.
- 41lithospherethe earths solid earth outer shell.
- 42biospherethe earths surface zone and it adjacent atmosphere in which all organic life exists.
