Document Summary
Population size changes as a result of four processes: birth, death, immigration, and emigration. N t = population size at time t. Concept 11. 1: population growth patterns, include exponential growth, logistic growth, fluctuations, and regular cycles. A single population can experience each of them at different times. This has altered forest composition, and co2 is released as the trees decay 17. 6 megatons every year: a sea in trouble case study: The comb jelly mnemiopsis leidyi was introduced accidentally into the black sea in the 1980s. Mnemiopsis is a voracious predator of zooplankton, fish eggs, and young fish. It continues to feed even when completely full, then regurgitates prey organisms stuck in balls of mucus. An individual mnemiopsis can produce up to 8,000 offspring just 13 days after its own birth. Birth and death rates do vary over time, thus we expect carrying capacity to fluctuate.
