In my hypothesis I state that yes‚ this will in fact affect the bio-diversity and the water will be more polluted in an area very obviously manipulated by humans. To test this‚ I have taken samples and collected data from ten locations‚ five in

Discuss the relative importance of physical and human factors in accounting for changes to vegetation over time within ecosystems in the British Isles (40 marks) The British Isles can be found in the Northern Hemisphere where deciduous forest is the main biome. Here physical and human factors have accounted for changes to the vegetation for many years. Human factors can include tourism‚ agriculture‚ urbanisation‚ interception and deforestation.

Temperature‚ soil‚ and the amount of light and water help determine what life exists in a biome. It is different from an ecosystem. An ecosystem is the interaction of living and non-living things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example‚ an aquatic biome can contain ecosystems such as coral reefs and kelp forests. 2. What are the 2 types of biomes? Give at least 5 examples for each type.

A habitat is an ecological or environmental area that is inhabited by a particular species of animal‚ plant‚ or other type of organism.[1][2] It is the natural environment in which an organism lives‚ or the physical environment that surrounds a speciespopulation.[3] A habitat is made up of physical factors such as soil‚ moisture‚ range of temperature‚ and availability of light as well as biotic factors such as the availability of food and the presence of predators. A habitat is not necessarily a
