Measuring population size is important for understanding Demographics, planning resource allocation, and assessing the impact of social and economic policies. It helps governments and organizations make informed decisions, identify trends, and address specific needs within a population.
The number of individuals in a population is called population size.
When the hare population increases, there is more food available for the lynx, which can lead to an increase in lynx population size. However, if the lynx population grows too much due to the abundance of prey, they may exceed their resources and face competition for food, which can eventually lead to a decrease in lynx population size.
POPULATION
The lynxes eat rabbits, so their effect is to reduce the rabbit population.
Um... why would you want too??

They do not. Population size does not affect the sample size. The variability of the characteristic that you are trying to measure and the required accuracy will determine the appropriate sample size.
Population size refers to the total number of individuals in a specific area, while population density is the number of individuals per unit area. Population size gives the total count of individuals, while population density provides a measure of how crowded or sparse the population is in a given area.
Population density is the size of a population that occupies a specific area. It is calculated by dividing the total population by the area they inhabit, usually expressed as individuals per square kilometer or square mile. It is a useful measure to understand how crowded or dispersed a population is in a given area.
Statistics often requires one to make estimates of some measure (variable) about a set of units. The total number of such units is the population size. Note that population, in this context, need not refer to people. If the study is about household expenditure on food (in some area), then the population is all households and the population size is the number of households (in that area). If the study is about diversity of insects in a field, the population may be all 1-metre squares in the field, and the size of the population will be the number of such plots - which will equal the area of the field.

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.

Population growth rate is the rate at which populations change in size over time as a fraction of the initial population. The formula used to measure growth rate is (birth rate + immigration) - (death rate + emigration).
