Competition for Resources
Density-independent factors regulate population growth
Variation in density-independent factors such as temperature and precipitation can cause dramatic changes in population size. For example, a drought or heat wave can cause a sharp increase in mortality rates, causing the abundance of a population to plummet.
Abiotic factors
oxygen availability
Water availability
A death rate that increases with population density or a birth rate that falls with rising density is said to be density dependent.
The salt concentration of water
A birth rate or death rate that does not change with population density is said to be density independent.
