population:all the members of a species living in the same place at the same time
density:the number of individuals per unit area or volume
dispersion: the relative distribution or arrangement of its individuals within a given amount of spaces
growth rate: birth rate minus death rate
reproductive potential: this rate is limited by the maximum number of offspring that each member of the population can produce
exponential growth: grow faster and faster
niche: the unique role of a species within an ecosystem
competition: is a relationship in which different individuals or populations attempt to use the same limited resources
predation: snakes eating mice,bats eating insects or whales eating consuming krill
parasitism: the relationship between the parasite and its host
mutualism: a close relationship between two species in which each species provides benefits to the other
commensalism: a relationship in which one species benefits and the other species is neither harmed nor helped
symbiosis: a relationship in which two species live in close association
