Term
|
Definition
| Matter that contains carbon and hydrogen. It may also contain other elements. It is found in living or deceased organisms. |
|
|
Term
|
Definition
| Matter that did not come from something that is or was living. It may or may not contain carbon. It is usually a mineral |
|
|
Term
|
Definition
| a process where by a plant uses the sun's energy to change carbon dioxide and water into carbohydrates and oxygen. The carbohydrates are used by plants to make their structures and to produce energy that is used in cellular functions. |
|
|
Term
Cellular Respiration [image] |
|
Definition
| is the reaction between carbohydrates and oxygen. It produces energy, carbon dioxide and water |
|
|
Term
Carbon Reservoirs [image][image] |
|
Definition
| areas that store and slowly release carbon. Includes oceans, forests and fossil fuels. |
|
|
Term
|
Definition
| Areas that absorb more carbon than they release. Two areas are forests and oceans |
|
|
Term
|
Definition
| coal, oil or gas formed when organisms that used photosynthesis die and are buried before they can fully decompose. If they are compressed they can form a fossil fuel. |
|
|
Term
|
Definition
A carbon reservoirs that gives off more carbon than it absorbs. Found when fossil fuels are burned or forests are cut down. |
|
|
Term
|
Definition
| the cycling of carbon through the ecosystems. |
|
|
Term
|
Definition
| Carbon containing compounds like carbone dioxide and methane gas, that act like the glass of a greenhouse by trapping the heat from the sun in the atmosphere |
|
|
Term
|
Definition
| The warming effect created by the ability of the Earth's atmosphere to trap thermal (heat) energy |
|
|
Term
|
Definition
| is the path that oxygen takes as it goes through a number of ecosystems |
|
|
Term
Aerobic Respiration [image] |
|
Definition
| Respiration that uses oxygen to release the chemical energy in carbohydrates |
|
|
Term
Anaerobic Respiration or Fermentation [image] |
|
Definition
| the releasing of energy from carbohydrates without the use of oxygen. Used by some bacteria; they give off methane, ethyl alcohol and acetic acid instead of carbon dioxide and water. |
|
|
Term
|
Definition
| Movement of nitrogen between the biotic and abiotic parts of the biosphere |
|
|
Term
|
Definition
The first step in the Nitrogen cycle. Nitrogen for nitrogen gas is combined with hydrogen to make ammonia |
|
|
Term
|
Definition
| kinds of plants such as peas, peanuts, soybeans, clover , alfalfa, alder and lupins that have nitrogen fixing bacteria in the nodules of their roots. |
|
|
Term
|
Definition
| a form of nitrogen containing both nitrogen and oxygen that is easily dissolved |
|
|
Term
|
Definition
| The process where nitrate is produced from ammonium |
|
|
Term
|
Definition
| the changing of ammonia and nitrate back into nitrogen gas. Is converted by a group of bacteria that are anaerobic. |
|
|
Term
|
Definition
the path of phosphorus through ecosystems. It comes from the weathering of sedimentary and metamorphic bedrock |
|
|
Term
|
Definition
| Ions of phosphate that can be dissolved out of rock and then into soil or water through the process of weathering. They then become available to producers and other organisms in the food chain. |
|
|
Term
|
Definition
| Microscopic fungi that live near the roots of most plants. The fungi increases the solubility (ability to dissolve) of phosphate, making it more readily available for the plant. The plant provides the fungi with carbohydrated made during photosynthesis. It is a symbiotic relationship. |
