CHAPTER5 SECTION 1 SC B-6: The student will demonstrate understanding of the interrelationships among different organisms & the biotic & abiotic components of their environment

1. Geographic Distribution 2. Density 3. Growth Rate

 # of individuals / unit area varies depending on species and ecosystem

1. # of births 2. # of deaths 3. #s that immigrate & emigrate

 occurs when the individuals in a population reproduce at a constant rate  *under ideal conditions with unlimited resources, a population will grow exponentially  see J-shaped curve

 growth pattern in which a population’s growth rate slows or stops following a period of exponential growth  carrying capacity: largest # of individuals of a population that a given environment can support
