|
Saprobiotic microorganisms |
A name for decomposers. |
|
|
Combustion |
Burning. |
|
|
Greenhouse gas |
Gases such as methane and carbon dioxide which in the atmosphere causes more heat to be trapped, so raising the temperature at the Earth's surface. |
|
|
Carbon dioxide |
The most common greenhouse gas. |
|
|
Climate change |
The change in temperature due to greenhouses gases and global warming |
|
|
Decomposition |
The digestion of things that were once living. |
|
|
Fossil fuels |
When decay is prevented and the dead matter is buried in layers and becomes carbon-containing compounds. |
|
|
Deforestation |
The removal of trees (and forests) which results in more carbon dioxide in the atmosphere and less oxygen. |
|
|
Global warming |
The overall temperature of the Earth, when increased due to greenhouse gases. |
|
|
Greenhouse effect |
A natural process that occurs all the time and keeps the average temperature at around 17 degrees Celsius. |
|
|
Saprobiotic nutrition |
The nutrition gained by dead matter that is absorbed by saprobionts. |
|
|
Ammonification |
The production of ammonia from organic ammonium containing compounds. |
|
|
Nitrification |
To oxidise ammonium to nitrites, which are then oxidised to nitrate. |
|
|
Nitrogen fixation |
The process of converting nitrogen gas into nitrogen-containing compounds. |
|
|
Denitrification |
To remove nitrogen or nitrogen-containing compounds from something. |
|
|
Xerophytes |
A plant adapted to living in dry conditions. |
|
|
Active transport |
Movement of a substance across a membrane from a region of low concentration to a region of high concentration. |
|
|
Aerobic |
Connected with the presence of oxygen. |
|
|
Anaerobic |
Connected with the absence of oxygen. |
|
|
Fertiliser |
A nitrogen-containing substance that increases the productivity of plants. |
|
|
Leaching |
The process by which nutrients are removed from the soil. |
|
|
Eutrophication |
The process by which nutrients build up in bodies of water, such as lakes and rivers. |
|
|
Nitrifying bacteria |
Microorganisms that convert ammonium compounds to nitrites and nitrates. |
|
|
Fertilisers |
A nitrogen-containing substance that increases the productivity of plants. |
