Producers - organisms that produce their energy from the sun., Primary Consumers - an organism that gets its energy from eating producers., Secondary Consumers - organisms that get their energy by eating primary consumers., Tertiary Consumers - organisms that get their energy from eating secondary consumers.
Biome - a region of earth inhabited by a community., Biosphere - layers of soil, water, and air that sustains life., Ecosystem - a group of organisms that interact with each other and the enviornment., Community - populations of organisms that interact in an ecosystem., Population - a group of the same species in the same area at a given time.
Desert - a landscape or region that recieves an extremely low amount of precipitation, less than enough to support growth of plants., Temperate deciduous forest - a forested biome found in mid-latitude temperatures and dominated by deciduous vegetation., Rainforest - forests characterized by high rainfall, with diverse plant and animal life., Grassland/Savannah - a grassland ecosystem characterized by the trees being small or widely spaced enough so that the canopy does not close., Coniferous Forest - a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest.
Freshwater Biome - a low-saline aquatic biome thata ccounts for 1/5 of the earth's surface., Aquifer - a geological formation that contains water., Water Pollution - the contamination of water bodies., Point Source - where water pollution is caused by a single identifyable source., Non-pont Source - where water pollution is caused by many sources together.
Biotic Factors - living factors in an ecosystem., Abiotic Factors - non-living factors of anecosystem that affect living organisms.
Secondary Succession - succession that occurs in places where an ecosystem has been damaged., Pioneer Species - the first species to move into an ecosystem at the beginning of succession, Climax Community - a community at the end of succession that is in equilibrium with little or no change in species.
Carrying Capacity - the maximum population size of a species that an enviornment can sustain indefinitely., Exponential Growth - when a population has a constant birth rate through time and is not limited., Sustainability - when a population has the capacity to endure over time., Logistic Growth - growth in a population with limited resources and space., J-curve - when on a graph, the population curve initially falls, then rises to above where it started., S-curve - A pattern of growth in which, in a new environment, the population density of an organism increases slowly initially, then increases rapidly approaching an exponential growth rate; but then declines in a negative acceleration phase until the population balances out., Population Growth Rate - the rate at which a population changes over time.
Industrial Revolution - a period in the 18th - 19th centuries where technology greatly increased, allowing the human population to increase as well.
