Organism
individual living things
Population
a group of the same species that live in an area.
Community

Biodiversity

Types of symbiosis & examples
mutualism
commensalism
parasitism
Mutualism
an interspecies interaction in which both organisms benefit from one another
ex) Lesser long-nosed bat & Saguaro
Commensalism
a relationship between two organisms in which one receives an ecological benefit from another, while the other neither benefits nor is harmed.
ex) human & demodiods
Parasitism
a relationship similar to predation in that one organism benefits while the other is harmed.
ex) hornworm & brachial
Carrying Capacity
the maximum # of individuals of a particular species that the environment can normally consist of and support.
Population Density
a measurement of the number of individuals living in a defined space.
