Biodiversity Edexcel Answer

Explain how physical factors influence the distribution of biodiversity shown (10 marks) at that go forth atomic number 18 several factors influencing biodiversity including; isolation, epoch, altitudinal range, productiveness The most bio diverse argonas be amongst the tropical of cancer and the tropic of Capricorn. The Philippines, Indonesia and Malaysia choose over 3000 imbed species per 10000 km2 because theyre uninvolved as a serial of islands which means in that spatial relation are more endemic species on the island as species come up in a more clean-cut way. The location within the tropics combined with the old age of the countries mean higher(prenominal) biodiversity as the species cast off more measure to develop and evolve. existence within the tropics means there are less physical constraints such as outsmart off and piddle which are all in abundance call commensurate to rain forest conditions. The Himalayas have over 4000 instal species per 10000 km2 collect to the extended altitudinal range which means more climatic zones are involved creating more diverse habitats such as argument faces, steep hills. This means there are more species able to live in these different climatic zones as they convey different conditions. Productivity is the key influencing factor for biodiversity, the location mingled with the tropics has the highest biodiversity because this area provides the key conditions for captureth of plants.

There is the optimum temperature, water, and sunlight to allow photosynthesis to take place which enables the plant species to grow an d develop more freely. Russia and Australia! generally have a bring down biodiversity due to the extensive level of disturbance from gay phylogenesis which destroys habitats and reduces the area for which species can live in. They also are relatively flat so dont have a great altitudinal range, they each have a large area which is possibly the main factor cause them to have some biodiversity. With reference to a named orbiculate ecosystem, value the global and local value of its goods and services (15 marks) Tropical...If you want to get a full essay, order it on our website: OrderCustomPaper.com
