__Unit 1 Final Project__

A biome is large regions that have similar biotic and similar abiotic components. organisms in the environment. Biomes are in many different terrestials such as tundra,boreal forest,temperate deciduous forest,temperate rainforest,grassland, tropical rainforest,desert,and permanent ice.
 * __Biomes:__**
 * Biotic ** are the living organisms in the environment and ** abiotic ** are the non-living

This relates to the oil spill in theGulf of Mexico,because for example the oil spill has harmed wetlands.Like in the boreal forest there are wetlands and these wetlands filter our water, help grow food, and are a home to thousands of plants and animals. So the oil spill would affect the **biotic** components such as plants and animals and it would also affect the ** abiotic ** components such as soil.

An ecosystem has oxygen,water,nutrients,light, and soil that interact with biotic components. This relates to the oil spill,because the oil spill has affected the ocean. The ecosystem has water and the cells of most living things contain between 50 and 90 percent water. With the water being affected because of the oil spill no organism can live without water and water carries nutrients from one place to another. Without nutrients there wont be plant and animal growth. The oil spill will reduce the amount of oxygen available to the plants.
 * __Ecosystems:__**



There is energy that is available for every trophic level and when one is affected or harmed then there wont be a next one. This relates to the oil spill,because the oil spill has harmed many organisms. With little vegetation the ecosystem cannot support many organisms.
 * __Ecological pyramid__**

The cycles are carbon cycle,nitrogen cycle,and phosphorus cycle. Photosynthesis is an important process in which carbon through ecosystems. This relates to the oil spill because the plants aren't getting the light to grow because the oil is covering the plants from getting sunlight. This will also affect the animals who eat these plants.
 * __Nutrient cycles__**
 * Photosynthesis ** a chemical reaction that converts solar energy into chemical energy.

Bioaccumulation ** is the gradual build-up of these chemicals in living organisms.
 * __Effects of Bioaccumulation on Ecosystems__
 * Biomagnification ** is the process in which chemicals not only accumulate but become more concentrated at each trophic level.So if the oil spill is accumulating then thats when it can harm. If the oil bioaccumulates and becomes biomagnified then the chemical is being stored in the plant tissue and the fat tissue of animals. If this occurs then keystone species can be affected, ** keystone species ** are species that can greatly affect population numbers and the health of an ecosystem. This relates to the oil spill, because the oil spill occured in the ocean and it affected many fish and without the fish other animals wont have food or they will eat the dead fish that are contaminated with the oil and that will harm the other animals who eat fish.

__**How Changes Occur Naturally in Ecosystems**__ This relates to the oil spill in the Gulf of Mexico, because in the ocean there could be species that were developed from a single species and if its harmed then there wont be anymore.
 * Adaptive radiation ** is the change from a common ancestor into a number of different species that "radiate out" to inhabit different niches.

__** Contamination ** is very harmful to living things, because of the oil spill lots of living things have been contaminated. ** Overexploitation ** is the use or extaction of a resource until it is depleted which can result in extinction. ** Extiction ** is the dying out of a species. This oil spill can cause extinction because many animals and plants have died. The oil spill has also caused habitat loss, ** habitat loss ** refers to the destruction of habitats,which usually results from human activities. The oil spill can destroy a habitat and without it, it cant support the original species that lived there.__

Native species ** are plants and animals that naturally inhabit an area. This relates to the oil spill,because if the oil spill affected the native species then the habitat is not able to support a diversity of wildlife.

__COMMENT ON WIKISPACE__ Wikispace has helped me a lot because it lets me put my own words on the information we have learned and it let me sees other students work which also makes it easier to understand what were learning.


 * __How Natural Phenomane Can Affect Climate!

VOLCANIC ERUPTIONS__** The atmospheric pollution from a major volcanic eruption can affect the climate over one to two years.Major volcanic eruptions can inject dust and sulphur dioxide in gaseous form up to 10 miles into the atmosphere. Smaller volcanic eruptions can inject sulphur dioxide but it would be removed within days bv rain. The volcanic dust and aerosols in the stratosphere may remain for up to two years, spreading ove the globe by winds years, spreading over the globe by winds.

-Surface waters off the coast of Ecuador and Peru get unusually warm and that is known as the El Nino. The warm water can result in unusually mild weather. This is how El Nino effects the climate. - La Nina brings cooler-than-normal waters to the surface in the eastern Pacific Ocean. __El Nino and La Nina cause unusally weather,which affects the climate.__
