Biodiversity

Science 9

TermDefinition
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).
