Bears are biotic factors. They are consumers, which means they eat and consume other plants and animals, making them omnivores. Bears live in the mountains and in the forest. They usually eat grass, roots, berries, and fish. Bears hibernate in the winter time. This means that they eat lots before the winter comes, and then the go into a cave of some sort and fall into a deep sleep. http://www.defenders.org/sites/default/files/styles/large/public/grizzly-bear-harry-bosen-dpc.jpg www.defenders.org
This is an abiotic factor. It is a sign. It is abiotic because it is not living. It does not need food, water, air, energy, or a suitable living condition is survive and thrive in.
Conks are biotic factors. They are one type of decomposer. It breaks down the trees dead manner. This helps because conks are one of the few things that can break down dead tree manner. A conk lives on the tree and that is it's habitat. http://www.walterreeves.com/uploads/JPGs/conk1.JPG www.walterreeves.com
Trees are biotic factors. They are producers. They provide oxygen as well as food for other animals. They provide oxygen for us using the process of photosynthesis. Trees can also provide fruit so that humans or animals can eat as well. Trees are a vital part for humans because they provide oxygen for us. If we didn't have oxygen, then we would not be living right now. Trees need water, soil, and sunlight to survive. Their habitat is anywhere where they can get what they need to survive. http://www.edmonton.ca/environmental/documents/TreesAndUrbanForestry430_2.jpg www.edmonton.ca
Fences are an abiotic factor in the ecosystem. They are a human disturbance to the ecosystem. They prevent the animals from roaming free in the environment. If there was a water stream behind the fence and there were fish in there, and if bears were on the other side of the fence, they could not get some of their source of food, which would be fish. This is an unintended consequence because we put it there to protect us from falling or getting attacked or etc. but we don't realize that there are other animals that need to use the space as well. This also connects to the path that we made because that also disturbs the animals and other biotic factors in the ecosystem. www.fencecenter.com
Bees are very important to the ecosystem, as pretty much everything is, but bees play a special role in the ecosystem. Bees pollinate the flowers. This helps them to grow and be bright and beautiful. Pollination is needed for plants to reproduce. When bees collect pollen from a flower, the pollen sticks to their hairs and then it falls off on other flowers. This is called mutualism. Which means that the flower and the bee both benefit. This is a symbiotic relationship.<br /> upload.wikimedia.org
Grass is a biotic factor. It is a producer. It provides food for other animals. Grass can also help erosion from happening from the soil below it. http://mkalty.org/wp-content/uploads/2014/07/grass_003.jpg mkalty.org
Moose are biotic factors. They are consumers. Their habitat is the outdoor woods. They have special warming fur to help them adapt to the weather. Moose are herbivores which means that they only eat plants to survive. http://www.epa.gov/glnpo/image/vbig/104.jpg www.epa.gov
Mushrooms are biotic factors. They are decomposers. This means that they break down dead matter and decay. Some mushrooms are poisonous but others can be eaten. A mushroom&apos;s habitat is usually grass. Other times, it can be in other places, but this is depending on what type of mushroom it is.<br /><br /> s2.thingpic.com
This is a symbiotic relationship. It is called parasitism. It is when one factor (the mosquito) benefits, while the other (human) is harmed. When the mosquito sucks blood from the human, they get their source of food that they need to survive. But for humans, we get a nasty bite that is very itchy. Some people are actually allergic, so they could even be more severe consequences. http://upload.wikimedia.org/wikipedia/commons/1/11/Mosquito_Tasmania_crop.jpg upload.wikimedia.org
This is a symbiotic relationship. Is is an example of commensalism. It is when one organism benefits, and the other is neither benefited, nor harmed. This is an orchid on a tree. Orchids use trees to help them grow and reach the sunlight. Although the orchid is using the tree, the tree is not affected by this. http://gallery.photo.net/photo/13394127-md.jpg gallery.photo.net
Rocks are abitoc factors. They can provide shelter and homes for other creatures. They also help us to build things. http://sciencenetlinks.com/media/filer_thumbnails/2011/10/28/rocks1.jpg__480x274_q85.jpg sciencenetlinks.com
Soil is an abiotic factor in the ecosystem. It helps other plants and trees grow. If we didn&apos;t have soil, we wouldn&apos;t have plants. Soil also helps provide habitats for many other animals and bugs. http://terrasoil.ca/wp-content/uploads/2012/05/topsoil.jpg terrasoil.ca
When heat from the sun melts the snow on top of mountains, it goes into the soil and the river. It then evaporates into the sky. This forms clouds. When the clouds get too heavy, precipitation happens. This includes rain, sleet, hail, and snow.This whole process happens again and it is called the water cycle. Clouds are abiotic factors in the environment. http://www.metoffice.gov.uk/media/image/j/i/Cumulus_2.jpg www.metoffice.gov.uk
These nails from the bridge are an abiotic factor. They do not need anything to survive. They help the bridge to stay together. http://www.grovehardware.com/wp-content/uploads/2013/12/construction-nails-300x200.jpg www.grovehardware.com
Air is all around us. It is an abiotic factor. If we did not have air, we would not be living right now. We need oxygen to survive, otherwise we would be long gone.
Wind can be one type of natural disturbance in an ecosystem. Very strong winds can blow away and kill many biotic factors. They can also take away abiotic factors in the ecosystem. One example would be if there were very, very strong winds, then it could blow away all the soil and rocks. This could take away the habitats of many animals. Worms need soil to survive, so the worms could die. Birds need worms to survive, so the birds would die. Bigger birds would eat them, bobcats would eat them, and so much more would die. http://cleantechnica.com/files/2014/04/wind-turbines17.jpg cleantechnica.com
The carbon cycle is the flow in carbon dioxide. It starts with all the CO2 (carbon dioxide) that comes from all of the factories and cars, as well as humans and other animals. Plants use the CO2 the make their food. It also helps to make O2 (oxygen). We then breathe in O2 and out CO2. The whole process begins again.
Food webs are many food chains linked together. An example would be if a bird ate a worm, and then a bigger bird ate the small bird, and then if a bobcat ate that bird. Platypus can also eat worms and fox can eat platypuses. This is an example of a food web.
