Term | Definition |
Resource partitioning | Relates to evolutionary change in species in response to selection pressures generated by interspecific competition. |
Mutualism | Mutualism is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other. |
Biological diversity | Also called biodiversity, biological diversity is often used to refer to the total number of different species on Earth. |
Population | A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, |
Parasitism | In biology/ecology, parasitism is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host. |
Ecosystem | An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. |
Community | a group of people living in the same place or having a particular characteristic in common. |
Species | a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g., Homo sapiens. |
Commensalism | In ecology, commensalism is a class of relationships between two organisms where one organism benefits from the other without affecting it |
Genus | A principal taxonomic category that ranks above species and below family, and is denoted by a capitalized Latin name, e.g., Leo. |
Variability | Variability is a measure of the spread of a data set. Learn more about the different measures of variability including the range, variance, and standard deviation, and how they are used in the field of Psychology. |
Niche | The function or position of a species within an ecological community. A species's niche includes the physical environment to which it has become adapted as well as its role as producer and consumer of food resources. |
Symbiosis | Interaction between two different organisms living in close physical association, typically to the advantage of both. |
Interspecies competition | Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resource in an ecosystem (e.g. food or living space). |
