Firstly abiotic components support the life functions of biotic components such as plants, animals and micro-organisms.. Abiotic components are affected not by the oil actually doing something to it but, by blocking off their routes or ways from getting to the biotic components. Biotic components can be affected in the terms of food. Since many of these aquatic plants and animals rely on the ocean for their main food supply they may begin to die off. Organisms in terrestrial areas may also be affected in the means of evaporation of water from the ocean. This water could fall to the earth in the form of precipitation that can land on plants and animals who might unknowingly ingest the harmful substances, that may lead to sickness or death. Another problem for both biotic and abiotic components in aquatic and terrestrial habitats is that each component has special adaptations that help them survive, but when new things are introduced into their habitats like in this case the oil spill the organisms have to make new adaptations in order to survive.

Because of the to the oil spill most of the plants and animals both on land and in water may have alot of big problems in finding food,becasue of the fact that the animals wont be able to find food, thir going to compete for it with eachother and then because of that the species may die out.Both abiotic and biotic components interacting with one another can help run an ecosystem.Plants in water need light to go thrugh a process called photosynthesis which converts solar energy into chemical energy that is usable for the plant.But, becasue of the oil spill the sun cant shine through the thick oil. So the pants on the bottom of the cean will DIE.

2.2 :
The Carbon cycle is the essential component of cells and life-sustaining chemical reactions. Carbon is cycled through living and decaying organisms, the atmosphere, bodies of water, soil, and rock. It moves between store by 6 processes : photosynthesis, cellular respiration, decomposition, ocean processes, volcanic eruptions, and forest fires. But, due to the oil spill many of these processes can’t be carried out properly or can cause damage to the organism. For example when there is oil in the ocean the plants down beneath can’t receive sunlight which they need to carry out the process of photosynthesis. Another example would be cellular respiration the process in which carbon dioxide is released back into the atmosphere. This process can cause harm to organisms in the means of them breathing them in after they have breathed is out which in this case could be evaporated oil.

Carbon Cycle
Without the proper use of the carbon cycle the world can change.The amounts of the oil spill will impact the carbon cycling and the Gulf of Mexico.,It will affect regular photosynthesis and cellular decomposition. There will be more carbon entering plant leaves and reacting with oil-covered water in the presence of little sunlight to produce poor energy sugars during photosynthesis. During cellular respiration, less energy will be released within the cells of the affected organisms and made available for unhealthy growth and reproduction. Also, alot of organisms will die during this catastrophic times, rate of decomposition will increase pretty fast. Having decomposers such as fungi and bacteria convert more organic molecules such as cellulose back into carbon dioxide and released into the atmosphere. Also, there will surely be a time where available carbon will decrease due to Carbons turning into rocks and sediments that will take centuries to be able to be used again.

Some of these processes include bioaccumulation, biomagnifications, and bioremediation.
Bioaccumulation- the gradual build-up of chemicals in organisms which in this case could be oil. Chemicals or oil can enter an organism through food intake, skin contact, or respiration. If the intake of chemicals such as oil is too much it can be harmful to the organism. Since there is so much oil in the water and some moving on land both terrestrial and aquatic organisms can be affected.
Biomagnification- the process in which chemicals not only accumulate but become more concentrated at each trophic level. Since the organisms in the lower trophic levels will be affected more then others because they are consuming most of the contaminated food. This leads to keystone species. These are very important species that can affect entire population and the health of an ecosystem. So, if even one of these species dies off the entire ecosystem can suffer. This leads to bioremediation.
Bioremediation- the process in which micro-organisms or plants help clean them up. But if these organisms are being affected by the oil spill then bioremediation cannot take place. Meaning that the oil will remain as it is until, human efforts are made to get rid of it.

3.2 How Human Influence Ecosystems
Due to the oil spill many habitats will be lost. Since the oil spill is a human accident, the animals and other organisms are the ones to suffer since they themselves cannot do anything about it or clean the mess. Habitat loss results from animals losing their homes from destruction of the ecosystem. Humans use much of the resources of the world and sometimes even over use them for agriculture, industry development, mining, and forestry. This includes land use, and deforestation. These two are major problems the humans put themselves and other organisms in.
Soil Degradation- water and wind erosion removes topsoil from bare land.
Soil Compaction- soil particles are squeezed together from farm vehicles and grazing animals.

3.3 How Introduced Species Affect Ecosystems
The oil spill can also affect native species which are the species that originally or naturally inhabit an area. Due to the spill, many new things may be introduced into the ecosystems of the Gulf in order to clean up the spill, Since they are able to completely change an ecosystem, these new introduced species can put an end to the native species of the area.
Introduced invasive species affects native species. They do this through competition, predation, disease, parasitism, and habitat alteration

Competition- Organisms compete for food sources and habitats.Predation- introduced species can have a bigger impact on prey than native predators. This is because prey may not have the adaptations to fight against them.
Disease and Parasites- Less dominant species have a chance to harm other species. Immune systems of organism can be severely affected from diseases.Habitat Alteration- Organisms take over other organisms’ habitats. They change structures such as light and oxygen levels, precipitation levels, pollination, soil chemistry, and nutrient cycling.

what wiki is to me:
I think that the wiki spaces is a differnet and i helpful way to do projects. It's different way but it more better than if i were to present it . I also think doing it over the computer is better becasue you can add in cool designs that can make it more pretty. Many people are already on the computer anyways on facebook and msn or even myspace and this way they can do this project while there on the computer. Also becasue i find this better.


El nino and la nina are the most powerful natural phenomena across the world; they are also the events that alter the climate of the Earth the most.So what exactly are El Nno and La Nina? the answer to that is simple:
  • El Nino is the condition when the atmosphere and ocean currents cause a movement of warmer water to the eastern Pacific. There is kind of a snowball effect when the process begins that can result in severe warming of the ocean off the northern west coast of South America. This prevents water from deeper in the ocean from upwelling to the surface.
  • La Nina is the opposite condition, when warm water builds up in the western Pacific Ocean, often causing drought conditions there and leaving northern South America with floods and northern North America with mild, wet summers and drought in the southeastern United States.

The weather when an El Nino or La Nina year occurs sounds pretty much like this:

El Nino Weather
La Nina Weather
  • Rain and flooding along the Pacific coast
  • Warm water disrupts food chain of fish, birds, and sea mammals
  • Tornadoes and thunderstorms in southern US
  • Fewer than normal hurricanes in the Atlantic
  • Snow and rain on the west coast
  • Unusually cold weather in Alaska
  • Unusually warm weather in the rest of the USA
  • Drought in the southwest
  • Higher than normal number of hurricanes in the Atlantic

So how do El Nino and La Nina directly affect us? In the winter of an El Nino year Canada tends to have much warmer weather especially around Manitoba and Ontario. Almost a full 3 degrees higher then usual; southern B.C. also tends to receive a lot less snow then on average. During a La Nina year the waters of B.C are a lot cooler, the overall temperature is below average, and Canada receives a lot more precipatation then usual. It affects BC directly by making us receive a lot more snow then usual.

Interesting Facts about El Nino and La Nina:
  • El Nino was first discovered hundreds of years ago by fishermen off the coast of Peru.
  • El Nino means "Little Boy" and was named after the Christ child, because it usually starts around Christmas.
  • El Nino is officially called ENSO - El Nino Southern Oscillation.
  • La Nina means "Little Girl." It is also called El Viejo, which means "old man," or an ENSO cold event.
  • La Nina occurs roughly half as often as El Nino
  • El Nino and La Nina are the most powerful phenomenon on the earth and alter the climate across more than half the planet.
  • El Nino may be caused by underwater volcanoes in the Pacific.
