Ecology
| Question | Answer |
|---|---|
| Ecological footprint | measure of human demand on Earth's ecosystems |
| Biodiversity | variety of life |
| Habitat fragmentation | process in which habitat loss results in smaller more isolated remnants |
| Stability | state of being stable |
| Ecological Disturbance | a change in the environmental conditions that causes a change in an ecosystem |
| Greenhouse gases | gas that contributes to the green house affect |
| Acid Rain | type of rain made up of dilute acids, a by product of heavy industry |
| Biological magnification | process where certain substances (pesticides or heavy metals) move up the food chain rivers-fish-humans |
| Deforestation | permanent destruction of forests to make land available for other uses |
| Dessertification | process where fertile land become dessert |
| Sustainability | capacity to endure |
| Agriculture | growing a dependable amount of food |
| Monoculture | farming strategy of planting 1 productive crop year after year |
| Renewable resource | resource that can be produced or replaced by healthy ecosystem functions |
| Nonrenewable resource | resource that can't be replenished by natural process within a time |
| Sustainable resource | using natural resources to meet our needs without causing long-term environmental damage |
| Limiting factors | environmental conditions that limit the growth, abundance and distribution of an organism or populations of organisms |
| Density dependent limiting factor | factors that affect the population individuals ex disease |
| Density independent limiting factor | effects will kill a population regardless on how big or small it is |
| Competition | interaction between organisms for resources |
| Density(population) | measure of #organisms that make up a population in a defined area |
| Distribution | how organisms are spread out |
| Age structure | how organisms are spread out according to their age |
| Immigration | how many organisms are coming |
| Emmigration | how many organisms are going |
| Exponential growth | growth rate when resources are unlimited |
| Logistic growth | occurs when the growth rate decreases as the population reaches carrying capacity |
| Carrying capacity | number of organisms an environment can support |
| Ecological succession | observed process of change of an ecological community over time |
| Primary succession | one type of biological and ecological succession in plant life in environments that lack soil or vegetation |
| Secondary succession | series of changes that take place in previously crowded, disturbed ecosystem |
| Pioneer species | hardy species that are first to colonize disturbed ecosystems, starting a chain of ecological succession with biodiversity |
| Ecology | study of organism and their environment |
| Ecosystem | biological community of interacting organism and their environment |
| Biotic | Living factor |
| Abiotic | non-living factor |
| Resourse | Any necessity of life |
| Biosphere | all the ecosystems on the planet |
| Biome | multiple communities ex, forest... |
| Community | group of different populations that live together in an area |
| Population | group of organisms of the same species in the same area |
| Autotroph | an organism that is able to form nutritional organic substances from simple inorganic substances |
| Primary Producer | organisms that produce biomass from autotrophs |
| Heterotroph | organism deriving its nutritional requirements from complex organic substances |
| Consumer | organisms that eat other things |
| Habitat | natural home or environment for organism |
| Niche | position or role taken by a kind of organism within its community |
| Resource | necessity of life |
| Predation | preying of one animal on others |
| Herbivory | eating of plants especially ones that are living |
| Symbiosis | interaction between 2 different organisms living in a close physical association |
| Mutualism | type of symbiosis |
| Parasitism | where one benefits and the other is harmed |
| Commensalism | class of relationships between 2 organisms where one benefits from the other without affecting it |
