Question | Answer |
Biomes | described by vegetation, vegetation determined by temperature and precipitation, north to south=tundra, grassland, tropical rain forest |
Savanna | grazing animals |
Grasslands | threatened by erosion, rich soil |
Tropical Rain Forest | animals are specialized to avoid competition, buttresses, vines, large flat leaves in understory, eagles, bats, and snakes in emergent layer, threatened by deforestation |
Deserts | dry side of mountain ranges |
Tundra | permafrost, fragile |
Taiga | coniferous forest, shape accumulates snow to insulate trees |
Chaparral | fire is beneficial, plants resprout from small amounts of vegetation, coastal and Meditarranean |
Temperate Deciduous Forest | squirrels, bears, deer eat nuts, berries, and leaves |
Temperate Rain Forest | high humidity, mosses, lichens, ferns, large evergreens, moderate temps |
Latitude | distance north or south of equator |
Estuaries | fresh and marine water, nutrients from rivers and oceans, many pollutants |
Coastal pollution | industrial waste and sewage |
Swamps | flat, poorly drained land, woody shrubs and water loving trees |
Marine | most organisms in shallow coastal waters, threats=runoff, discharge, overfishing, nets, sewage, algal blooms |
Rivers | widen, slow, and warm as the move to flatter ground |
Lakes | have regions with little sunlight |
Wetlands | remove water pollutants, plentiful nutrients, perceived as disease infested, diverse, marshes, swamps |
Ponds | organisms depend on sunlight, temperature, nutrients |
Littoral | diverse and abundant life |
Benthic | cool dark water |
Nekton | swims freely |
Benthos | attached to a surface |
Open ocean | organisms depend on nutrients |
Coral reefs | formed by secretion of calcium carbonate, threatened by oil spills, pesticides, sewage |
Salt marshes/ mangrove swamps | provide habitats, found along coast, threatened by development, high salt content |
Population Density | number of individuals per unit area |
Parasite | roundworm, ticks, mistletoe, cause host to be more vulnerable |
Predator=prey | lynx and hare, predator kills prey |
Random dispersion | solitary organisms |
Density independent deaths | storms |
Reproductive potential | bacteria have high potential, increase potential by reproducing earlier in life |
Ants and acacia trees | mutualism |
Niche | organisms role in the environment |
Carrying capacity | determined by supply of the most limited resource |
Commensalism | symbiosis where one benefits, the other is unharmed |
Mutualism | symbiosis where both organisms benefit |
Parasitism | symbiosis where one organism benefits and the other is harmed |
Population | number of individuals in an area |
Habitat | location an organism lives |
Competition | can occur between populations, within a population, between overlapping niches |
Biotic potential | maximum number of offspring each individual can produce |
Surface water | less than 1% of all of Earth’s water |
Fresh water | most is in the north and south poles |
Water treatment | chlorine kills bacteria |
Water management | diverts water to where it is needed |
Conservation | low flow showerheads, allows more freshwater to use |
Point source | easily identified source of pollution |
Nonpoint source | runoff |
Groundwater | difficult to clean because it is deep, pollutants cling, recycling takes a long time |
Ocean pollution | pollutants come from land |
1990 Oil pollution act | double hulled tankers |
Watershed | largest in US is Mississippi River |
Phosphates | begin process that kills fish |
Water use conflicts | upstream country builds a dam |
Dams | decreased construction because of environmental concerns, create energy, both sides of the dam change |
Aquifers | hard to purify |
Water pollution | effects multiply through food chain |
Thermal pollution and eutrophication | decrease dissolved oxygen |
Climate | long term conditions |
Atmosphere | warm air rises and cold air sinks |
Carbon Dioxide since 1958 | higher high amounts and higher low amounts |
Latitude | influences climate due to how much sun hits the earth |
Ozone layer | polar regions, seasonal, years to reverse, chlorine is released from clouds in the spring |
CFC’s | 10 to 20 years to reach stratosphere |
Greenhouse gases | trap heat |
Ultra violet radiation | damage genetic material |
