1.1 Biomes:

Biomes: A major regional or global biotic community, such as a grassland or desert, characterized chiefly by the dominant forms of plant life and the prevailing climate. There are nine different types of biomes : -boreal forest -tundra -temperate deciduous forest -temperate rainforest -desert -tropical rainforest -grassland -permanent ice -aquatic biomes The oil spill that had happend in the Gulf of Mexico only effected the aquatic biomes , reason for that being was the sea creatures .

1.2 Ecosystems:

Ecosystem : An ecological community together with its environment, functioning as a unit. Organisms in the community are always interacting with eachother, in exchange for different reasources. the habitat for the animals has changed, and the oxygen levels have reduced because of the excessive amounts of oil. Photosynthesis also has no way of taking action because the sunlight is unable to reach plants at the very bottom of sea level. The different kinds of species may also be harmed because of the toxins in the oill . there for numbers in marine animals may decrease.

2.1 Engergy Flow in Ecosystems:

Engery flows from producers such as plants - primary consumers - secondary and tertiary consumers. A good example of this would be a picture of a food web or hiearchy chart. Oil that has been spilt , limits valuable nutrients to reach marine animals , who need that to be energetic.

2.2 Nutrient Cycles in Ecosystems:

the earth's biosphere seals all nutrients that areneeded for organisms to survive. The carbon cycle is an extreamly important component of cells and chemical reactions. The carbon cycle plows its way through living and decaying organisms. It can happen in six different stages , photosynthesis, cellular respiration, decomposition, ocean processes, volcanic eruptions, and forest fires. The oil spill doesnt allow any of the marine animals to recive sunlight or good nutrients , it instead feeds them with toxins.

2.3 Effects of Bioaccumulation on Ecosystems:

All foul chemicals are absorbed by different things in the environment. Plants and fat tissues in herbivors and carnivors are some examples. Chemicals can enter an organism through food intake, skin contact, or respiration. Oil, would not be a good intake to any living organism.

3.1 How Changes Occur Naturally in Ecosystems :

Ecological succession is the process in which ecosystems change over time. Mainly effected is, Primary succession. Primary seccesion occurs in areas where no soil exists, such as glaciation or lave flow. The food chain becomes effected her aswell because they rely on others and others on others for food .But if all of them become ill , the whole entire population would become effected.

3.2 How Humans Influence Ecosystems:

We humans have caused many issues for not only ourselves , but for the animals that even we rely on. Think about it , if all the fish in the sea were effected by this oil spill we would also loose valuable nutrients to our own bodies. We destroyed the way the animals in the ocean were living , and took them away from their habitats. 3.3 How Introduced Spieces Affect Ecosystems:

The Gulf of Mexico oil spill can also effect native species that are in the area. The reason for this being them relying on those specific food sources that have been toxicated by the oil.

How Can Climate Be Influenced By Human Activity ? Think about it , " GO GREEN " is a term often used. But does anybody really stive to make a difference in how much we really do pollute the enviornment ? No, not really. Our own lifestyles are what has caused such a large negative amount of impact on the earth it self. Everyone can make a difference, recycling is a good example. We can all recycle its a simple no cost favour your paying to the earth. Unesessary gases such as : methane, carbon dioxide, and nitrous oxide kill our planet . Methane: - What is methane ? Methane is a colorless, oderless gas that has a wide distibution in nature. It's the " principal component " of natural gas. - How is it harmful to our planet and where does it come from ? Methane is a natural gas that occurs in raservoirs beneath the the surface of the earth. But before it is distributed some sort of processing takes place. Some methane can be found through out the distillation of coal. ( Coal is a combustible rock formed from the remains of decayed vegetation. ) Carbon Dioxide: -What is CO2 ? Carbon dioxide is an inorganic chemical compound. This compound exists naturally from the earths enviornment. - How was it discovered ? In the 1600's people began to think about carbon dioxide , but they were unsure on what to call it. Joseph Black, a Scottish chemist who identified carbon dioxide and explored many of its properties. By the 1800's, people had succeeded in creating and studying other forms of carbon dioxide, such as its solid form. Yes, climate can be effected by human activity. But are you as an individual, going to try and make a change ? external image recycle-bin.png external image RecyclingRebecca_blacklogo_o_large.jpg Bibliography: -BC Science 10 Textbook. -http://scifun.chem.wisc.edu/chemweek/methane/methane.html -http://www.wisegeek.com/what-is-carbon-dioxide.htm
