Term
|
Definition
| Involve the storage of chemical elements in nutrient pools, or compartments, and the transfer, of nutrients between pools. |
|
|
Term
|
Definition
| The amount of a particular nutrient stored in a portion of an ecosystem. |
|
|
Term
|
Definition
| Moving nutrients between the pools of an ecosystem. |
|
|
Term
|
Definition
| A part of the biosphere where nutrients are absorbed faster than it is released. |
|
|
Term
|
Definition
| A portion of the biosphere where nutrients are released faster than it is absorbed. |
|
|
Term
|
Definition
Light energy is trapped in organic molecules.
Organic molecules are broken down to release energy used in metabolism
Energy is not recycled. |
|
|
Term
|
Definition
| molecular forms of elements (C, N, P) that are used to build cells |
|
|
Term
|
Definition
Essential for energetics, genetics, and structure of living ystems(ATP,RNA,DNA)
Phosphorus is slowly released to terrestrial and aquatic ecosystems through the weathering of rocks and absorbed by plants which recycle it to the ecosystem. |
|
|
Term
| Where are Phosphorus deposits found? |
|
Definition
| The largest quantities of phosphorus occur in mineral deposits and marine sediments. |
|
|
Term
| Nutrient Nitrogen importance |
|
Definition
Important to the structure and functioning of organisms.
Key biomolucles such as amino acids, nucleic acids, and hemoglobin |
|
|
Term
|
Definition
| Nitrogen can be found in major atmospheric pools in the form of molecular nitrogen (N2) |
|
|
Term
|
Definition
Change N2 to a usable form NH3.
1. Cyanobacteria, or blue green algae etc.
2. Certain free-living soil bacteria
3. bacteria associated with roots of leguminous plants
4. Actinomycetes bacteria |
|
|
Term
| Nitrogen Available to plants |
|
Definition
| Through fungi and bacteria NH3 (ammonium) becomes NH4, and NO3 (nitrate) and can be used directly by plants. |
|
|
Term
|
Definition
| The process of nitrogen leaving an nutrient pool. |
|
|
Term
|
Definition
| Used in fertilizers and burning fossil fuels. |
|
|
Term
|
Definition
| C02 (carbon dioxide), CH4 (methane), influences global climate |
|
|
Term
|
Definition
| Moves through the atmosphere through photosynthesis and respiration. |
|
|
Term
| Photosynthesis and respiration effects on carbon? |
|
Definition
Photosynthesis removes carbon from the atmosphere
Respiration by primary producers and consumers, decomposers returns carbon back to the atmosphere. |
|
|
Term
|
Definition
| must first dissolve in water before being used by aquatic primary producers. |
|
|
Term
|
Definition
| the breakdown of organic matter accompanied by the release of carbon. |
|
|
Term
| Rate of Decomposition is influenced by? |
|
Definition
| Temperature, moisture, and the chemical composition of both plant litter and the environment. |
|
|
Term
| Heat and Moisture on decomposition |
|
Definition
| More moisture and heat helped the leaves to decompose faster. |
|
|
Term
| Herbivory effects on nutrient cycling |
|
Definition
| Grazing on grass can lead to higher levels of nitrogen in baby grass. which in turn effects the grazing habits of heavy grazers like bison. |
|
|
Term
| Detrivore effects on the nutrient cycle |
|
Definition
| Burrowing and building mounds can increase heterogeneity in soil nitrogen and light penetration. |
|
|
Term
|
Definition
| Increasing heterogeneity in soil nitrogen in oceans and water. |
