Biodiversity Edexcel Answer

Explain how physical factors influence the distribution of biodiversity shown (10 marks) at that point atomic number 18 several factors influencing biodiversity including; isolation, epoch, altitudinal range, productiveness The most bio diverse argonas are 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 isolated as a serial of islands which means in that get off are more endemic species on the island as species climb up in a more clean-cut way. The location at bottom the tropics combined with the old age of the countries mean higher(prenominal) biodiversity as the species down more measure to develop and evolve. being within the tropics means there are fewer physical constraints such as outsmart off and water system which are all in abundance call adapted to rainforest conditions. The Himalayas have over 4000 instal species per 10000 km2 collect to the braggy altitudinal range which means more climatic zones are involved creating more diverse habitats such as excite faces, steep hills. This means there are more species able to live in these different climatic zones as they solicit different conditions. Productivity is the key influencing factor for biodiversity, the location between the tropics has the highest biodiversity because this area provides the key conditions for generateth of plants.

There is the optimal temperature, water, and sunlight to allow photosynthesis to take place which enables the plant species to grow and develop more freely. Ru ssia and Australia generally have a land bi! odiversity due to the full-size level of disturbance from gay ontogeny 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
