Introduction

Usman Majeed 5/17/09 IB Bio Year 1 Planet Earth Ecosystem Essay The world is a large biosphere that we live in, formally known as planet Earth. Some populations uncontrollably seem to grow while others tend to dwindle. It's a dog eat dog world, and humans, are at the top of the food chain. Planet Earth talks about the delicate ecosystems and fragile animals that live in them, as well as how their numbers are beginning to die out. Poaching seems to be the main reason why animals seem to become endangered. Unfortunately however, there are several other reasons why animals can be threatened with extinction such as human interference, pollution, and diseases. ...read more.

Middle

A large problem that is seen in many exotic countries such as Africa where precious animals like elephants, tigers, and rhinoceros reside poachers are extremely threatening. Poachers kill animals deliberately for one reason: to make profit off of them. Elephants for example, have large ivory tusks which are very valuable in the black market. Another variable in animal life is that of pollution. Pollution can be things such as waste, oil spills, etc. Acid rain and water pollution have been devastating for many species of fish and birds. Many animals can be caught in many plastic items and others may even attempt to eat left over food or other trash. ...read more.

Conclusion

Also because many trees are inevitably cut down from forests the only thing we can do is to find alternate ways of using wood, and we can also help by planting trees or "replenishing" the environment so to speak. Because plants are the basis of any ecosystem it is vital that they are prevalent, thus planting new vegetation is essential to survival not only for animals, but for humans as well. Humans can also help by providing research for eradication and prevention of certain diseases and plagues in specific ecosystems. Scientists continue to research and provide new ways to fight diseases and furthermore help species from extinction. As an added help by humans many national reserves and wildlife parks are being developed all over the world to protect and help breed endangered species in order to ensure their continuation of life on our beloved planet Earth. ...read more.

    A probable reason for this missing protein is that the organism is conserving energy and resources, only producing CBP when conditions are guaranteed to be low in calcium. Thus, it is apparent that the evolution of the parasitic yeast form from the mycelial form was dependent on the incorporation of the CBP1 gene into the fungal genome.

    These include the lips, tongue and larynx and three areas of the brain, the speech motor cortical area and two further areas also on the left side of the cerebrum. One of these areas store auditory, visual and verbal information, and the other is involved in formulating statements and response, that is putting words together.

    lack of a functional honing facet on the third premolar, which means the canines do not rub against the premolar during chewing. This is also a distinct ape feature. It does retain strong crown asymmetries, in particular enlarged buccal cusps on the upper and lower premolars.

  2. Rain forests.

    In addition to trees, rain forests support a great variety of bamboos, herbs, and shrubs. Climbing vines, ferns, mosses, and orchids grow directly on the trunks and branches of large trees. Because of continual moisture and warmth, tropical rain forests stay green all year.

  1. Comparison of the species diversity of the vegetation of upland and lowland ecosystems.

    Soil types affect the plants directly because plants rely on soil to provide them with water and nutrients. Soil can be acidic, alkaline or neutral. Alkaline soils are alkaline because they are on limestone (calcarious). Acidic soils are acidic due to peat, which is mainly on moor soils.
