Vocab and
| Term | Definition |
|---|---|
| Community | All living things in an are |
| Ecosystem | All living or non-living in an area |
| Biome | Large area with similar climate conditions that determine plant and animal species there |
| Resource partitioning | Different species using the same resource in different ways |
| Temporal partitioning | Using the same resource but at different times |
| Spatial partitioning | using different areas of land that's shared |
| Morphological partitioning | Using diff. resources based on diff. evolved body features |
| Bacterial Fixation | Certain bacteria that live in soil or in symbiotic relationship with plant, convert Nitrogen into ammonia |
| Synthetic Fixation | Humans combust Fossil Fuels to convert Nitrogen into Nitrate |
| Assimilation | Plants and Animals taking in Nitrogen and incorporating it into their body |
| Ammonification | Soil bacteria, microbes and decomposers convert waste and dead biomass back to N3 and return it to soil |
| Nitrification | Conversion of ammonium into Nitrite by soil bacteria |
| Denitrification | Conversion of soil Nitrite into nitrious oxide |
| Biochemical Cycle | Movement of matter in the ecosystem |
| Reservoirs | Mass holding of a chemical |
| Human impact (Nitrogen) | Global warming, algae blooms. |
| Primary Productivity | Rate that solar energy is converted into organic compounds via photosynthesis |
| Respiration loss | Plants use up some of the energy they generate via photosynthesis by doing cell respiration |
| Gross primary Productivity | The total amount of sun energy that plants capture and convert to energy |
| Higher primary productivity | Diverse animal life, water availability, higher temp and nutrient availability |
| Precipitation | Atm. gas into surface water |
| Transpiration | Water from plant into Atm. as gas |
| Condensation | water vapor becomes liquid |
| Infiltration | Surface water becomes subsurface water |
| Phosphorus supply | Major natural source is weathering rocks that contain P |
| Synthetic (Phosphorus) | Mining P materials and adding to to products like fertilizers |
| Sedimentation (Phosphorus) | P forms solid sediments at bottom of ocean |
| Geo. Uplift (Phosphorus) | Tectonic plates force layers up, making mountains thus the cycle starts again |
| Carbon Sink | Ocean, Algae, Sediments, Plants, Soil |
| Carbon Source | FF combustion, Animal gas, Deforestation |
| Direct Exchange | CO2 moves into Atm. to ocean by dissolving in and out of water surface |
| Long term Carbon reservoir | sediments that are pressed together at ocean floor |
| Ecosystem Diversity | Number of different habitats In given area |
| Species Diversity | Number of different Species in an area |
| Genetic Diversity | How different the genes are of individuals within a population |
| Richness | The total number of different species found in ecosystem |
| Evenness | Measure of how all of the balances between the different species |
| Bottleneck Event | Environmental Disturbance that drastically reduces pop. size and reduces genetic diversity |
| Inbreeding depression | Leads to higher chance of offspring having harmful genetic mutations |
| Resilience | The ability of an ecosystem to return to original conditions after a major disturbance |
| Natural Disruptions | A natural event that disrupts the structure and or functions of an ecosystem |
| Provisioning | Goods taken directly from ecosystem or made from natural resource (wood, paper, food) |
| Regulating | Natural ecosystem regulate climate quality reducing storm damage and healthcare cost |
| Supporting | Natural ecosystems support processes we do ourselves making them cheaper and easier |
| Cultural | Money generated by recreation or scientific knowledge |
| Primary Succession | Starts with bare rock, in an area with no previous soil formation |
| Secondary Succession | Starts with already established soil, in an area with disturbance, which cleared out life |
