Land Succession
land biomes and land succession
| Question | Answer |
|---|---|
| All organisms genetically similar enough to breed and produce live, fertile offspring in nature. | species |
| All members of a species that live in the same area at the same time. | Population |
| - All populations living and interacting in an area. | Community |
| A biological community and its physical environment. st | Ecosystem |
| Living or once-living factors | Biotic |
| Non-living factors | Abiotic |
| Areas sharing similar climate, topographic and soil conditions, and roughly comparable communities. | Biomes |
| series of interconnected food chains in an ecosystem. | Food Web |
| refers to the amount of biomass produced in a given are during a given time | Productivity |
| refers to an individual’s feeding position in an ecosystem. | Trophic Level |
| Primary consumers; eat plants. | Herbivores |
| Secondary or tertiary consumers; eat other animals. | Carnivores |
| Secondary or tertiary consumers, eat both plants and animals | Ominvores |
| Breakdown complex organic matter into simpler compounds. Feed on all trophic levels. | Decomposers |
| states that some energy is lost every time it is transferred in the form of heat | Second Law of Thermodynamics |
| The total energy transferred from one trophic level to the next can be estimated with the ____________. | 10% rule |
| Only about 10% of the energy present in one __________ can be transferred successfully to the next ____________. | trophic level, trophic level |
| The main abiotic factor in determining ecosystem type is __________. | climate |
| Distances north and south of the equator | Latitude |
| __________ is height above sea level. | Altitude |
| _____________ gains and loses heat much more slowly than air. | water |
| Biomes near a large lake or ocean generally have more _________ temperatures. | stable |
| A climatograph is a combination __________________ graph for a given biome. | precipitation and temperature |
| Low moisture levels (less than 25cm of precipitation a year) Rainfall is infrequent and unpredictable | Desert |
| Often located on the leeward side of mountains High number of succulent plants Can survive for long periods without water | Desert |
| Animals bury themselves underground and hibernate during the dry season | Desert |
| Hottest and driest land biome. Located near the equator. Lowest amount of plant and animal life | Tropical Deserts |
| Seasonal temperature changes. More moisture than tropical deserts, less than grassland | Temperate Deserts |
| Located just below the Arctic Circle. Characterized by perfrost | Polar(ice) Deserts |
| More precipitation and cooler temperatures than deserts. Mostly grasses, wildflowers, and shrubs. | Grasslands |
| Located near the equator, usually between desert and rainforest biomes | Tropical Grasslands(Savannas) |
| Hot during the summer, freezing during winter. Similar precipitation to temperate deserts, but mostly as snow and ice | Polar Grasslands(Tundra) |
| More than 200 cm annual rainfall. Hot temperatures year-round | Tropical Forests |
| Poor soil and unable to support continued farming | Tropical Forests |
| Top layer of tropical forest; Contains most of the fruits and flowers Also contains most of the animals | Canopy |
| Ground Layer of tropical forest. Very bottom Mostly occupied by decomposers | understory |
| Deciduous trees shed leaves when water is scarce or ground is frozen. Not as diverse as the rainforest | Temperate Rain Forest |
| Located anywhere the elevation rises 3000 feet or more above sea level. Air gets colder and drier as you get higher and higher | Mountains |
| During this type of ecological succession this is the community that develops initially. | Pioneer Community |
| During this type of ecological succession this is a mature community that develops after many years. | Climax Community |
| Located just below the Arctic Circles. Long, harsh winters. Short growing season | Taiga |
| Boundaries between adjacent communities | Ecotones |
| During Ecological Succession, the community that develops initially | Pioneer Community |
| Permanently frozen soil layer found in the tundra biome | permafrost |
| characterized by brilliant tree foliage during the fall season | temperate decedious forest |
