In the Amazon Rainforest‚ new research is being done that has completely changed the way that we now see the Amazon. European accounts from centuries ago‚ tell of large Amazonian cities all up and down its banks. This idea was thought to be untrue due to finding that the Amazon soils were not actually fertile at all. But‚ that idea is now being challenged‚ with the finding of‚ terra preta. The reason that I decided to choose this topic is because I think it needs much more attention than it is given

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water

Describe and explain the seasonal variations in climate in a tropical region (10 marks) The seasonal variations in climate‚ in a tropical region‚ which includes temperature‚ precipitation and wind direction‚ are due to a number of factors. The tropical continental climate in Africa‚ north of the equator‚ can be described as transitional‚ as it is between the rainforest margins of the central African rainforest and also

BORNEO RAINFOREST The tropical rainforest is earth’s most complex biome in terms of both structure and species diversity. Tropical Rainforests can be found in South and Central America‚ Africa‚ Oceania (the islands around Australia)‚ and Asia (15).Tropical rainforests cover only about 7% of the Earth’s surface (13‚ )All Tropical Rainforests have similar characteristics including climate‚ precipitation‚ etc. They are located in a band around the equator.

The Madagascar rainforest is just another ecosystem‚ it actually acts as a home to many endangered species including the silky sifaka‚ sportive lemur‚ and the red-ruffed lemur. Another very important species that is indigenous to this rainforest is the rosy periwinkle‚ which is used to cure leukemia. Furthermore‚ rainforest are distinguished by receiving

Brazilian Rainforest is home to a myriad of exotic animals‚ each equipped with their own fair share of abilities to survive in the wild. There are one thousand seven hundred species of birds‚ six hundred ninety-five amphibious species‚ six hundred fifty-one species of reptiles and five hundred seventy-eight mammalian species (Butler‚ 2014). In Brazil resides one-third of the world’s rainforests‚ which is nestled right around the Earth’s equator (Butler‚ 2014). As a result‚ the rainforests experience

Many of the main causes of the rainforest destruction include: logging‚ agriculture-shifted‚ cultivators‚ agricultures-cash‚ crops and cattle‚ ranching‚ fuelwood‚ large dams‚ mining and industry‚ colonization schemes‚ and tourism. In most cases‚ this is untrue due to the nature of rainforests and of logging practices. Large areas of rainforest are destroyed in order to remove only a few logs.

Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession". why it occurs Every species has a set of environmental conditions under which it will grow and reproduce most optimally.
