Biodiversity Edexcel Answer

Explain how physical factors influence the distribution of biodiversity shown (10 marks) at that take aim atomic number 18 several factors influencing biodiversity including; isolation, epoch, altitudinal range, productiveness The most bio diverse argonas argon amongst the equatorial of cancer and the tropic of Capricorn. The Philippines, Indonesia and Malaysia choose over 3000 imbed species per 10000 km2 because theyre free as a serial of islands which means in that can are more endemic species on the island as species set out in a more clean-cut way. The location deep down the tropics combined with the old age of the countries mean higher(prenominal) biodiversity as the species take up more measure to develop and evolve. existence within the tropics means there are less physical constraints such as outsmart off and water system which are all in abundance call adequate to rain forest conditions. The Himalayas have over 4000 instal species per 10000 km2 collect to the astronomic 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 engage different conditions. Productivity is the key influencing factor for biodiversity, the location surrounded by the tropics has the highest biodiversity because this area provides the key conditions for deformth of plants.

There is the optimum temperature, water, and sunlight to allow photosynthesis to take place which enables the plant species to grow and develop more freely. Russia and Australia generall! y have a lower biodiversity due to the bad level of disturbance from gay outgrowth which destroys habitats and reduces the area for which species can live in. They also are comparatively 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 world(a) 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
