Others will not be able to compete and die out9) a factor that affects the population regardless of the population size ex. natural disasters, seasonal cycles, human activities (damming, deforestation), unusual weather, etc.10) a community of organisms living and interacting with each other and abiotic (non-living) parts as a system 12) any factors limiting the population which are dependent on the number of individuals in the population14) the available resources to a population16) increased competition for food/habitat, prey population decreases, the predator will starve, making prey population go up again, making the predator population go back up17) the proximity of the disease influences the spread of disease
