The assignment is the activity sheet trees and carbon
The more trees there are, the more filters for the air. To simplify things, trees act kind of like the filter in your air conditioner. They breathe in carbon dioxide and spit out (or release) oxygen. Of course, we need the oxygen to breathe.
Carbon cycle is also called as carbon fixation, it explains how carbon compound in the environment are converted from one compound to another compound.
Just like water cycle where water circulate from oceans to environment to clouds to rain and finally reaches earth again, which involve evoporation, condensation, and finally water reaches earth by means of rain and the water cycle continues.
Similarly just like water cycle in carbon cycle one compound is converted into another compound. The carbon dioxide present in the environment is utilised by plants via photosynthesis so carbon dioxide became part of plant, which is utilised to produce carbohydrates. Carbohydrates is consumed by animals and humans and thus became part of humans now. Humans releases out carbon products in the form of faeces or when a human die and it is burned or buried it release out carbon dioxide which is utilised by plants and the carbon cycle continues.
All living things contain carbon. Trees absorb carbon in the form of carbon dioxide and fix the carbon via the process of photosynthesis into glucose. The formula for glucose is C6H12O6 and it is called a carbohydrate. When a consumer eats the plant which contains glucose, the carbon becomes incorporated into their body. All living things carry out respiration and carbon dioxide is released to the environment. When trees are removed due to deforestation, excess carbon dioxide builds up in the atmosphere. This leads to global warming.
This PDF file is an advanced and detailed explanation of the carbon cycle in nature. You must be in an advanced class in order to be asked and expected to work with this material, which includes formulas for calculations pertaining to the carbon cycle. The first thing you must do is read the PDF file. Then you may ask a specific question pertaining to one aspect or element of the material you don't understand.
In the meantime, in brief, the carbon cycle is the system by which carbon is exchanged between the atmosphere, the earth and the water. Carbon is released into the atmosphere from the natural sources of detritus and water, especially ocean water, and from the unnatural sources of industry and our living environments (e.g., homes). Carbon is returned from the atmosphere to vegetation, especially trees, and ocean surfaces and our living environments. The carbon cycle is critical--and critically balanced--to the sustainability of life on Earth.
We are here because of the trees.
Carbon cycle is also known as carbon fixation.
The movement of carbon, in a many forms in the environment, between the biosphere, atmosphere, oceans, and geosphere is described by the carbon cycle.
- During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product. Carbon dioxide is slightly soluble and is absorbed into bodies of water such as the ocean and lakes.
- Combustion occurs when any organic material is burned in the presence of oxygen to give the products of carbon dioxide and water and energy. The organic material can be any fossil fuel such as methane, oil, or coal.
- Combustion/metabolism oxygen is used and carbon dioxide is a product.
