- 1Define Adaptive Radiation?When a common ancestor species evolves to fill variety of different niches in an ecosystem.
- 2Define Aeration?Process of removing small plugs of soil, allowing air and water to get into the soil and reducing soil compaction. `
- 3Define Climate Change?Long term changes in the climate of an area (temperature, precipitation, etc.)
- 4Define Deforestation?The process of logging and clearing forests, without replanting them.
- 5Define Primary succession?Is area where there is soil.
- 6Define Secondary Secession?Is disturbed areas where there is soil.
- 7Define Extinction?The complete loss of a species of organisms.
- 8Define Foreign species?Organisms that have been introduced to an ecosystem by humans.
- 9Define Greenhouse gases?Gases that absorb heat and radiate back into the atmosphere.
- 10Define Native Species?Organisms that naturally occur in an ecosystem.
- 11Define Natural Selection?Successful members of a species will survive and reproducers, creating change in population over time.
- 12Define ozone layer?An atmospheric layer coating ozone (O3) molecules which absorb much of U.V light from the sun.
- 13Define pioneer species?Organisms that begin primary succession in ecosystem.
- 14Define proliferation?An increase in the numbers of individuals with a new adaptive trait, as a result of natural selection.
- 15Define Stability?Constant dilate conditions in ecosystems.
