Oil spills affects the ocean and sea as it pollutes the water. It also affects the all living things from the oil itself because it has poisonous chemicals. This can affect them from both internal exposure to oil because they might inhale or ingest the poisonous chemical.
Oil spills impact a lot on the terrestrial ecosystem because they can cause a lot of pollution too. For example, the Kuwaiti oil fires caused a lot of air pollution. So this can cause a lot of sustainability in the terrestrial ecosystems. It can also affect some marine animals. If it affects marine animal then there are a lot of chances of them to die and oil spills happen really often. So a lot of marine animals will die which can affect the sustainability of the aquatic ecosystems.
The government of Canada is using a modern and coordinated approach to manage the impact of human activities ,like oil spills, on Canada's oceans and making important progress in protecting the marine areas. The government also undertakes the important science, research and monitoring the problems in our ecosystem and find out and effective way.
Human activities can really affect aquatic and terrestrial ecosystems in many ways. Some of those ways are, ocean pollution, change of landscape, and global climate change (ramp-alberta.org).
What is it?
Biodiversity is the variety of life.
I learned about how oil spills can affect the sustainability of the ecosystem not only underwater but also on the land because if the water is polluted then animals can’t drink that water and they survive on water. If the animals will die then there will be a huge imbalances in the ecosystem.
Photosynthesis & Cellular Respiration
Oil spills contaminates the water. So the plants under water can’t make their food (sugar) out of it. As the spilled oil floats on the surface of water, it blocks sunlight which is one the essential things that plants rely on.(http://homeguides.sfgate.com/oil-spill-affects-photosynthesis-79801.html)
Transfer Of energy
Transfer of energy in food chains
So first the plants make their own food by the process of photosynthesis in which they need sunlight and water, that are natural resources and they need carbon dioxide which is produced by living organisms like humans. When plants go under photosynthesis, they produce sugar and oxygen. So plants exhale oxygen and almost all living things need oxygen to live, so they inhale it. Then comes the process of cellular respiration in which all living thing eat the plants and use the plant's food to produce energy for themselves. So when they eat plants, the plant energy (sugar) in presences of oxygen is converted into energy by the mitochondria that is present in all cells and that works as energy for all the cells.
Oil spills impact plants a lot as it prevents the plants to go under the process of photosynthesis. Due to this, a lot of plants can die too. This will create a huge imbalance in the marine ecosystem as there will be no plants and the marine animals that only rely on plants for their survival will die too. Oils spills impact cellular respiration as it is dependent on photosynthesis. During cellular respiration, plant requires oxygen and glucose which is produced by plants through photosynthesis. If, because of oil spills, plants can’t do photosynthesis then they won’t get oxygen and glucose for respiration too, which can cause an imbalance in the ecosystem.
Oil spills affect the process of photosynthesis a lot as the plants under water can’t do photosynthesis. The reason it that the oils spilled blocks the sunlight. If plants can’t do photosynthesis, and cellular can't happen too because this process need sugar and oxygen produced by plants during the process of photosynthesis.
Types of spheres
It can affect all the 4 spheres. Lithosphere (land) can be affected because if the water gets polluted, then animals can’t drink that water or if they drink it, they will die resulting in imbalance in the ecosystem. Hydrosphere can be affected because oil spills prevent plants to go through photosynthesis by blocking the sunlight. Also the marine animals will die too because of the water pollution. Atmosphere can be affected because one of the ways to separate the oil from the water is to burn it. If the oil is burned, it will pollute the atmosphere.
WHat is it?
A healthy ecosystem is a sustainable ecosystem which means that means when the animals, plants and nonliving things are in harmony and there is nothing to disturb the ecosystem. When everything is done the way it should be and nothing that is a part of our ecosystem is in danger, that is a healthy ecosystem. Oil spills can affect the sustainability of the ecosystem as it creates a huge imbalance in the ecosystem.
ABiotic & Biotic
Water can be a factor because if it rain heavily then there are a lot of chances of flood and a lot of animals can be killed.
Wind could be another factor as it changes the environment by blowing of the seeds around.
Fire is another factors as if there is a lot of friction, then there can be fire in the forest and it can destroy the forest. If the forest is destroyed then the animals can die too or some animals will have to migrate.
Natural disaster can also affect the sustainability of the ecosystem. Earthquakes on high scale can affect as a lot of animals can die and the trees can fall too. Earthquakes also create mountains and the animals that can’t live on mountains will have to migrate from one place to another.
Humans can be a negative factor towards the sustainability of the ecosystem because humans need wood to make houses and more the population, the more they need wood. So they will cut a lot of trees for that and this will create a huge imbalance in the ecosystem as the animals that rely on trees will die too like deers. Also the animals that rely on those animals can die too like tiger rely on deers for their survival too.
Water can be a factor because almost all animals need water to survive. As these days, there are less drinking water resources, a lot of people will die because of that reason. Also due to a lot of human activities, the water is getting polluted. Like oil spills, and if the animals drink that water, they can die too. It is a problem for plants too as they can’t do photosynthesis. (http://www.nhptv.org/natureworks/nwep12a.htm)
Environment can be another factor because some animals need specific environment to survive. Some plants too need specific environment to grow.
I think oil spills affect both abiotic (water) and biotic (plants and marine animals) stuff. It can also result in limited source of water which can affect the population and the sustainability of the ecosystem.
Human activities affect soil composition in many ways. Some of those ways are farming, construction and mining ( http://www.classzone.com).
Affects on ecosystems
Human activities affect water quality in many ways. Some of those ways are overpopulation, agriculture, littering and commercial forestry (http://www.umgeni.co.za/water_education/wpwq.asp).
