‘The characteristics of the vegetation of tropical biomes are more the outcome of continued human activity than a response to the climatic conditions’. With reference to one tropical biome‚ discuss the extent to which you agree with this view. (40 marks) A tropical biome is a large community of plants and animals that occupy a distinct region. Tropical biomes are mostly located within the tropics‚ between the Tropic of Cancer and the Tropic of Capricorn and currently cover less than 5% of the Earth’s

The tropic rain forest is one of the major biomes and it consist of four levels‚ the forest floor‚ the emergent layer‚ canopy layer‚ and the understory level. The rain forest is also home to much biodiversity. 2. What changes happening in Madagascar are posing challenges for lemurs? Give details about the sources‚ time scale‚ and types of change. Habitat destruction is the major change‚ it is caused by humans moving into the lemurs area and cutting

Using two contrasting case studies‚ discuss management schemes in fragile environments. A fragile environment is when there the balance between climate‚ soils‚ vegetation‚ animal life and people could easily be upset and the ecosystem destroyed. In order to maintain a fragile environment dynamic sustainability needs to be established. An example of a fragile environment is the Serengeti National Park and Jau National Park.

Ancient forests around the world are in peril‚ but we can still save them. Governments and the timber industry need to understand what a crucial role they play in maintaining global biodiversity‚ not to mention how vital they are in regulating the climate‚ so they need to act now. And as consumers‚ we can all help to save the forests. Making sure that the wood and paper we buy has come from well-managed sources (or‚ even better‚ is 100 per cent recycled) is something we can all easily do. We have

A tropical rainforest is an ecosystem that occurs roughly within 28 degrees north or south of the equator (equatorial zone between the Tropic of Cancer and Tropic of Capricorn). They are characterised by their humidity (average of 88% in the rainy season and 77% in the dry season)‚ hot temperature (average 27.9 °C during the dry season and 25.8 °C during the rainy season) but more importantly their extremely high rainfall (torrential rainfall - between 1‚500 mm and 3‚000 mm annually).
