Biology Ch 3
| Term | Definition |
|---|---|
| Tolerance 3.1 | Ability of any organism to survive when subjected to abiotic factors or biotic factors. |
| Community 3.1 | Group of interacting populations that live in the same geographic area at the same time. |
| Ecological succession 3.1 | Process by which one community replaces another community because of changing abiotic and biotic factors. |
| Primary Succession 3.1 | Establishment of a community in an area with exposed rock that doesn't have topsoil. |
| Climax Community 3.1 | Stable, mature community that results when there's little change in the composition of species. |
| Secondary Succession 3.1 | Orderly and predictable change that takes place after a community of organisms has been removed but the soil has remained intact. |
| Limiting Factor 3.1 | Abiotic and biotic factor that restricts numbers, reproduction or distribution of organisms. Sunlight, climate, temperature, water, nutrients, fire, soil, space, other living things |
| Temperate Forest (definition) 3.2 | Composed mostly of broad leaved, deciduous trees. |
| Temperate Forest (temp. & precipitation) 3.2 | yr Temp_ -30 degrees C - 30 degrees C |
| Biome 3.2 | Large group of ecosystems that share the same climate and have similar types of communities. |
| Climate 3.2 | Average weather conditions in an area, including temperature & precipitation. |
| Tropical Savanna (definition) 3.2 | characterized by grasses & scattered trees in climates that receive less precipitation than same other tropical areas. |
| Tropical Savanna (temp and precipitation) 3.2 | yr Temp_ 20 degrees C - 30 degrees C |
| Desert (definition) 3.2 | Area with low rainfall, whose annual rate of evaporation exceeds its annual rate of precipitation; can support cacti and some grasses and animal species such as snakes and lizard. |
| Desert (temp & precipitation) 3.2 | yr Temp_ 20-49 degrees C |
| Tropical Seasonal Forest (definition) 3.2 | Biome characterized by deciduous and evergreen trees, a dry season, and animal species that include monkeys, elephants & Bengal tigers. |
| Tropical Seasonal Forest (temp & precipitation) 3.2 | yr Temp_ 20-25 degrees C |
| Temperate Woodlands & Shrubland (definition) 3.2 | Open woodlands & mixed shrub communities with less annual rainfall than in temperate forests. |
| Temperate Woodlands & Shrubland (temp & precipitation) 3.2 | yr Temp_ 10-40 degrees C |
| Tundra (definition) 3.2 | Treeless biome with a layer of permanetly frozen soil. |
| Tundra (temp & precipitation)3.2 | yr Temp_ -34-12 degrees C |
| Temperate Grassland (definition) 3.2 | Biome characterized by fertile soils with a thick cover of grasses. |
| Temperate Grassland (temp & precipitation) 3.2 | yr Temp_ -40-38 degrees C |
| Boreal Forest (definition) 3.2 | Biome south of the tundra with dense evergreen forests and long, cold, dry winters. |
| Boreal Forest (temp & precipitation) 3.2 | yr Temp_ -54-21 degrees C |
| Tropical Rain Forest (definition) 3.2 | Hot, wet biome with year round humidity; contains earths most diverse species of plants and animals. |
| Tropical Rain Forest (temp & precipitation) 3.2 | yr Temp_ 24-27 degrees C |
| latitude 3.2 | The distance of any point on the surface of earth north or south from the equator. |
| Weather 3.2 | Atmospheric conditions such as temperate and precipitation at a specific place and time. |
| Limnetic Zone 3.3 | The open water area that is well lit and is dominated by plankton. |
| Aphotic Zone 3.3 | Area of the ocean that's too deep for sunlight to penetrate. |
| Intertidal Zone 3.3 | Narrow band where the ocean meets land. |
| Littoral Zone 3.3 | Area of lake on pond that's closest to the shore. |
| Benthic Zone 3.3 | Area of sand, silt and dead organisms along the ocean floor. |
| Wetlands 3.3 | Areas of land such as marshes, swamps and bogs that are saturated with water and that support aquatic plants. |
| Plankton 3.3 | Free floating photosynthetic autotrophs that live in freshwater or marine ecosystems. |
| Estuary 3.3 | Ecosystem that's formed where a freshwater, river or stream, merges with the ocean. |
| Sediment 3.3 | Material that's deposited by water, wind or glaciers. |
| Photic Zone 3.3 | Area of the open ocean to a depth of about 200 m that's shallow enough for sunlight to penetrate. |
| Abyssal Zone 3.3 | Deepest region of the ocean. |
| Profundal Zone 3.3 | Deepest areas of a large lake, much colder and lower in oxygen than the other two zones. |
