| Biomes | Groups of Similar Ecosystems, usually defined by the most conspicuous types of vegetation |
| 2nd Law of Thermodynamics | No transfer of energy is 100% efficient |
| Newton | wrote 2nd law of thermodynamics |
| Trophic Levels | producers, primary, secondary, tertiary |
| Succession | A change in species composition over time due to change in abiotic factors caused by organisms |
| Ecology | study of interrelationship organisms and their environment |
| Population | a group of organisms of the same species in one place at one time |
| Community | multiple organisms in one place at one time |
| Ecosystem | multiple species and the non-living environment in one place at one time |
| K (Carrying Capacity) | the # of individuals that can be supported under the current conditions |
| Intraspecific competition | competition between members of the same species |
| Interspecific competition | competition between members of a different species |
| Biotic | living things |
| Abiotic | non-living things |
| Exclusion | A species that is dying or dies out |
| Niche | aall physical attributes of an organism and the way that organism interacts with its envrionment |
| Population Dynamics | change in population |
| Biodiversity | number of different species in a given area |
| Tropical Rain Forest | occurs on lowlands near equator, moisture in the air |
| Savanna | tropical or sub tropical grassland with scattered trees and woodlands |
| Desert | severely hot and dry, low precipitation |
| Perrenial (vegetation) | plants that live more than one year, not found in desert |
| Succulants | plants having thick leaves with large cells able to store water (found in deserts) |
| Chapparal | brushland, small shrubs with tough leaves |
| Temperate grasslands | similar to savannahs except prarie trees grow only by streams |
| Temperate Deciduous Forest | develop thru midlatitude regions where there is enough moisture for large trees; high humidity, fertile soil |
| Taiga | goes across NA, europe, and asia above tree line (after which no trees can grow); characterized by harsh winters and short summers |
| Tundra | beyond tree line or at very high altitudes; plants compact, shrubby, and matlike |
