Relative population size is the size of an area's population as it compares to similar areas' populations. For example, the relative population size of a country would be what rank it had compared to the population of other countries.
A prey
The population size of a predator species is directly controlled the availability (population size, etc.) of its prey species.
There are many wetlands in California
Population density
From a sample of a population, the properties of the population can be inferred.
The sumation (each stratum of population) of risk * population size. For example: (risk*population size of group 1) + (risk*population size of group 2) + ... + (risk*population size of group n)
population dynamics-Population dynamics is the study of the factors that influence these changes in a population's size
In size, the USA. In population, Indonesia.
No. There aren't wetlands in Alabama.
Population density is determined by dividing the total population of an area by its total land area. It is typically expressed as the number of people per square mile or square kilometer. High population density indicates a crowded area with many people living closely together, while low population density suggests a more sparsely populated region.
In population genetics and population ecology, population size (usually denoted N) is the number of individual organisms in a population.
