| 6440655821 | Community | A group of interdependent organisms inhabiting the same region and interacting with each other |  | 0 |
| 6440655822 | Interspecific Interactions | interactions between 2 or more different types of species (includes competition, predation, herbivory, and symbiosis |  | 1 |
| 6440655823 | Symbiosis | the relation between two different species of organisms that are interdependent |  | 2 |
| 6440655824 | Competition | the struggle between organisms to survive in a habitat with limited resources |  | 3 |
| 6440655825 | Mutualism | symbiotic relationship in which both species benefit from the relationship. +/+ |  | 4 |
| 6440655826 | Commensalism | the relation between two different kinds of organisms when one receives benefits from the other without damaging it. +/0 |  | 5 |
| 6440655827 | Parasitism | a relationship between two species in which one species benefits and from the other species, which is harmed, involves a host |  | 6 |
| 6440655829 | Parasite | an organism that lives in or on another organism; one who lives off another person |  | 7 |
| 6440655830 | Predation | an interaction in which one organism captures and feeds on another organism. +/- |  | 8 |
| 6440655831 | Interspecific Competition | in a community competition for limited resources between members of different species |  | 9 |
| 6440655832 | Competitive Exclusion | The concept that when populations of two similar species compete for the same limited resources, one population will use the resources more efficiently and have a reproductive advantage that will eventually lead to the elimination of the other population, This principle can be used to predict fundamental ecological niches |  | 10 |
| 6440655833 | Carrying Capacity | largest number of individuals of a population that a given environment can support |  | 11 |
| 6440655834 | Ecological Niche | the sum of a species' use of the biotic and abiotic resources in its environment. Like a "profession". |  | 12 |
| 6440655835 | Fundamental Niche | The full potential range of the physical, chemical, and biological factors a species can use if there is no competition from other species. |  | 13 |
| 6440655836 | Realized Niche | the range of resources and conditions a species actually uses or can tolerate at optimal efficiency; smaller than fundamental niche | | 14 |
| 6440655843 | Herbivory | An interaction in which an herbivore eats parts of a plant or alga. +/- interaction |  | 15 |
| 6440655848 | Keystone Species | a species that is critical to the functioning of the ecosystem in which it lives because it affects the survival and abundance of many other species in its community |  | 16 |
| 6440655849 | Invasive Species | plants and animals that have migrated to areas where they did not originate; often displace native species by outcompeting them for resources (exotic species) |  | 17 |
| 6440655851 | Primary Succession | an ecological succession that begins in a an area where no biotic community previously existed |  | 18 |
| 6440655852 | Secondary Succession | succession following a disturbance that destroys a community without destroying the soil. Yellowstone Fire in 1988 for example. |  | 19 |
