These different parts interrelate and depend on each other. There is a balance between the different parts.The concept of an ecosystem. The use of a small scale ecosystem to illustrate the parts of an ecosystem and how it works, including consumers, decomposers, food chain/web, nutrient cycling and producers. The balance between the components. The impact of changing one component on the others. Also mentions the potential impacts of deforestation in area.AQA BUnit 2: Hostile WorldBrief mention of ecosystems, but in the context of Tropical RainforestsEdexcel ANo specific mention of ecosystems. Unit 3 Changes in the UK Countryside How the pressures and conflicts in a UK National Park are being managed. The pressure of increasing visitor numbersThe pressure of increasing visitor numbers leads to conflicts between different groups of people within the park. How are these pressures and conflicts being managed in one UK National Park. Edexcel BTopic 2: Climate and Change Natural climate change in the past has affected people and ecosystemsExamining the impact of a short-term, historical event such as the Little Ice Age on people and farmingTopic 3: Battle for the Biosphere The biosphere is being degraded by human actions.Using an example, e.g. Amazonia, to consider the role of human activity in direct destruction of the biosphere, e.g. deforestation, mining, conversion to farmland or over fishing. Degradation of the biosphere by indirect means, e.g. climate change induced stress.Topic 4: Water World Changes to the hydrological cycleConsidering the impact of climate change on the hydrological cycle and ecosystems, in areas which may experience increased aridity. Cultural Geography DevelopmentSustainable management of ecosystems, both locally and globally, to protect them from further degradation.OCR ANo relevant contentOCR BEcosystems are one possible theme for a Geographical InvestigationWJEC A Theme 9: Living Things What are biomes and how do they differ? How does the physical environment interact with living things to produce different large scale ecosystems? Identify the links between living and non-living parts of an ecosystem. Appreciate that ecosystems exist at different scales. How are ecosystems managed? In what ways do people use ecosystems? Identification and analysis of human impact on one located ecosystem to demonstrate the various ways in which it is being used such as: logging, agriculture, fishing.How can ecosystems be managed sustainably? Evaluate strategies such as ecotourism, selected logging, national parks, cycle ways and fishing quotasWJEC BKey Idea 7: Economic activity and ecosystems How can economic activity lead to changes in the structure, processes and stability of ecosystems?Investigations of the structure, function and influence of people / organisations on contrasting ecosystems at different scales. Use an ecosystem local to the school, offering the possibility of fieldwork, or choose from a variety of scales and locations. After an introduction to the effects of human activity on the chosen ecosystem use a debate to explore the views of different groups of people in relation to the issue and its sustainable exploitation. Presentation of results by an individual activity using, for example, a newspaper front page, Photo Story or two leaflets and an accompanying commentary.What conflicts arise from these changes both within and beyond the ecosystem?A consideration of how conflicts arise from tensions between the desire to create wealth and job opportunities and the need to protect ecosystems.How might ecosystems be better managed in a sustainable way?How ecosystems can be managed to reduce conflict and ensure a sustainable future WJEC B would seem to be the best opportunity for a specification to match with what Rose has been doing, and with the changing nature of the ecosystems on Bleaklow. It is also worth noting that National Parks and the way that they are managed feature in many specifications. One of the tensions in the work that Rose has been doing is the way that the area is still open for people to visit, when it would perhaps be best for it to be closed off in order to allow it to regenerate. There are also links with water management and supply.  2JKsty z { & ' n o D E F ϿtttttttteZZehhp6uCJaJhh/CJaJmH sH  hh/CJ^JaJmH sH  hhp6uCJ^JaJmH sH hhp6uCJaJmH sH hh&CJaJhh&CJaJmH sH hhw|5CJaJmH sH hh`K5CJaJmH sH hh&5CJaJmH sH hhp6u5CJaJmH sH KYast|^PPd$Ifgdkd$$IflF$J   t06    44 laytw|d$Ifgdw|{ G 8kd$$IflF$J   t06    44 laytd$Ifgdp6ud$7$8$H$Ifgd/d$7$8$H$Ifgdp6u E F R Gkd0$$IflmF$J   t06    44 layt $Ifgdd$Ifgdd$Ifgdw|R u |  d$7$8$H$Ifgdd$7$8$H$Ifgd/d$7$8$H$Ifgdw|    0 1 S T y z lmno·}lllllll hhbCJ^JaJmH sH hhbCJaJmH sH hh+CJaJ hh+CJ^JaJmH sH hh+CJaJmH sH hh/CJaJhhCJ^JaJhh/CJaJmH sH  hhCJ^JaJmH sH  hh/CJ^JaJmH sH *  ' = l^K888d$7$8$H$IfgduQOd$7$8$H$Ifgdw|d$Ifgdw|kd$$IflF$J   t06    44 layt= c ZL9d$7$8$H$Ifgdw|d$Ifgdw|kdr$$Ifl4F$`J   t06    44 laytw|d$7$8$H$IfgduQO Fpd$7$8$H$Ifgdbd$7$8$H$Ifgd MNVijkltijijudYdYJ9 hhCJ^JaJmH sH hhCJaJmH sH hhp6uCJaJ hhp6uCJ^JaJmH sH #hhp6u5CJ^JaJmH sH #hhb5CJ^JaJmH sH hhp6uCJaJmH sH hh+CJaJ hh+CJ^JaJmH sH hh+CJaJmH sH hhbCJaJ hhbCJ^JaJmH sH  hhCJ^JaJmH sH <^m_LL99d$7$8$H$IfgduQOd$7$8$H$Ifgdw|d$Ifgdw|kd$$Ifl4F$ J   t06    44 laytw|ZL9d$7$8$H$Ifgdw|d$Ifgdw|kd$$Ifl4F$ J   t06    44 laytw|d$7$8$H$IfgduQOMNVjkZL99d$7$8$H$Ifgdw|d$Ifgdw|kdL$$Ifl4F$ J   t06    44 laytw|d$7$8$H$Ifgd+kltn`MMd$7$8$H$Ifgdw|d$Ifgdw|kd$$IflF$J   t06    44 laytw|n`M::d$7$8$H$IfgdVd$7$8$H$Ifgdw|d$Ifgdw|kd$$IflF$J   t06    44 laytw|m  23bf BCqr{̺̺ޯ~~j_P̺̯PhhCJaJmH sH hhCJaJ&hhCJ\]^JaJmH sH  hhCJ^JaJmH sH  hhCJ^JaJmH sH hhCJaJmH sH hhCJaJ#hhCJ]^JaJmH sH #hhCJ]^JaJmH sH  hhCJ^JaJmH sH  hhCJ^JaJmH sH 9mnZLd$Ifgdw|kd$$Ifl4F$`J   t06    44 laytw|d$7$8$H$Ifgdb 3E7d$Ifgdw|kd$$Ifl4lF$ J   t06    44 laytd$7$8$H$Ifgdd$7$8$H$IfgdV qr{G9d$Ifgdw|kdV$$Ifl4F$ J   t06    44 laytw|d$7$8$H$Ifgdd$7$8$H$Ifgd4g{  (pd$7$8$H$Ifgdd$7$8$H$IfgdU {  89kl 9:jkVWopqrFGSTUstﻩ}}nhh&CJaJmH sH hhCJaJmH sH hhCJaJ#hhCJ]^JaJmH sH #hh6CJ^JaJmH sH #hh6CJ^JaJmH sH  hhCJ^JaJmH sH  hhCJ^JaJmH sH  hhCJ^JaJmH sH +pqrSm_LLL9d$7$8$H$Ifgdd$7$8$H$Ifgdd$Ifgdw|kd$$Ifl4F$`J   t06    44 laytw|STUm_LLd$7$8$H$Ifgdd$Ifgdw|kd$$Ifl4F$ J   t06    44 laytw|mkkkkkkd0 $$Ifl4F$ J   t06    44 laytw|thh/CJaJmH sH hhBCJaJmH sH hhCJaJmH sH hhUCJaJmH sH 21h:p/ =!"#$% $$If!vh#v#vJ #v :V l t0655J 5 ytw|$$If!vh#v#vJ #v :V l t0655J 5 yt$$If!vh#v#vJ #v :V lm t0655J 5 yt$$If!vh#v#vJ #v :V l t0655J 5 / yt$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l t0655J 5 ytw|$$If!vh#v#vJ #v :V l t0655J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4l t06+55J 5 yt$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|$$If!vh#v#vJ #v :V l4 t06+55J 5 ytw|j 666666666vvvvvvvvv666666>6666666666666666666666666666666666666666666666666hH6666666666666666666666666666666666666666666666666666666666666666662 0@P`p2( 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p8XV~ OJPJQJ_HmH nH sH tH J`J Normal dCJ_HaJmH sH tH DA D Default Paragraph FontRi@R 0 Table Normal4 l4a (k ( 0No List tt & Table Grid7:V0 dPOP "0Pa16d7$8$H$CJOJQJaJmH sH 4o4 "0A10B*CJ^JaJph@"@ " List Paragraph ^m$POP "0Pa23d7$8$H$CJOJQJaJmH sH POP "0Pa15d7$8$H$CJOJQJaJmH sH PK![Content_Types].xmlN0EH-J@%ǎǢ|ș$زULTB l,3;rØJB+$G]7O٭V$ !)O^rC$y@/yH*񄴽)޵߻UDb`}"qۋJחX^)I`nEp)liV[]1M<OP6r=zgbIguSebORD۫qu gZo~ٺlAplxpT0+[}`jzAV2Fi@qv֬5\|ʜ̭NleXdsjcs7f W+Ն7`g ȘJj|h(KD- dXiJ؇(x$( :;˹!
