Ipat model - i (environmental impact ) = p (people) x a (affluence) x t (technology) Environmental resistance - sigmoid curve (carrying capacity) R vs k reproductive strategies r = rapid reproduction, quick maturation, k = slow reproduction, long maturation. Total fertility rate (definition and factors influencing it) average number of offspring per woman, affected by education, socio-economic status, infant mortality, child-rearing costs. Demographic transition model: know stages and where developed vs developing countries preindustrial, transitioning, industrial, postindustrial.

Emergent properties complex patterns (simple- ant, emergent propety- complex behavior of the colony) Ecosystem (biotic (producers consumers and decomposers) and abiotic factors) Flows/transformations (water, energy (c), nutrients (n,p, k, s) and trophic dynamics.
