Document Summary

Population growth is not the change in the number of species during some period of time. Carrying capacity refers to the number of individuals who can be supported in a given area with in natural resource limits, and without degrading the natural, social, cultural and economic environment for present and future generation. Obligate mutualists live with a partner species. The carrying capacity for a given area is not fixed. Ecosystem processes do not include energy cycling and interaction among species for nutrients. Population size is defined as (pt2) = pt1 + b d + i e. Mutualism: an interaction between 2 or more species, where species derive a mutual benefit, for example an increased carrying capacity. Neutralism: the relationship between 2 species which interact but do not affect each other. Amensalim: an interaction between organisms or species, in which one species benefits at the expense of another.
