| Question | Answer |
|---|---|
| This refers to an organism’s reproductive patterns. | Life-history patterns |
| The number of organisms of one species that an environment can support indefinitely. | Carrying Capacity |
| These factors have an increasing effect as population increases – ex. Disease, competition, predators, parasites, and food. | Density-Dependent Factors |
| As a population gets larger it will reproduce at a faster rate. | Exponential Growth |
| The study of human population size, density and distribution, movement, it’s birth and death rate. | Demography |
| This refers to the number of deaths there are per 1000 population in a given year. | Death Rate |
| Refers to the number of live births there are per 1000 population in a given year. | Birthrate |
| These factors can effect populations regardless of the population size. | Density-Independent Factors |
| The time needed for a population to double in size. | Doubling Time |
| The proportions of the population that are in different age levels. | Age Structure |
| rain,snow, sleet, or fog with a pH below 5.6;causes the deterioration of forest, lakes, statues, and buildings. | acid precipitation |
| variety of life in an area; usually measured as the number of species that live in an area. | biodiversity |
| different environmental conditions that occur along the boundaries of an ecosystem. | edge effect |
| a species in which the number of individuals falls so low that extinction is possible. | endangered speices |
| nonnative species in an area; may take over niches of native species in an area and eventually replace them. | exotic species |
| the disapperance of a species when the last of its members dies. | extinction |
| damage to a habitat by air, water, and land pollution. | habitat degradation |
| seperation of wilderness areas from each other; may cause problems for organiamsthat need large areas for food or mating. | habitat fragmentation |
| layer of the atmosphere that helps to protect living organisms on Earth's surface from damaging doses of ultraviolet radiationfrom the sun. | ozone layer |
| when the population of a species is likely to become endangered. | threatened species |
| when members of a species are held by people in zoos or other conservation facilities. | captivity |
| field of biology that studies methods and implements plans to protect biodiversity. | conservitation biology |
| natural strips of land that allow the migration of organisms from one wilderness area to another. | habitat corridors |
| parts of the environment that are useful or necessary for living organisms. | natural resources |
| programs that release organisms into an area where their species once lived in hopes of reestablishing naturally reproducing populations. | reintroduction programs |
| philosophy that promotes letting people use resources in wilderness areas in ways that will not damage the ecosystem. | sustainable use |
