Should There Be Used To Predict How A Population Grows And Or Shrinks Over Time?

There are several ways to predict how a population grows and/or shrinks over time (Daempfle, 2016). Some organisms are tagged to measure their arrangement in a particular population. Human population is measured by a census. Population demographics teaches us about population size, density, and age. The information collected assists scientists in predicting how populations will change over time. Population size is the number of organisms in a population. Population density is the number of organisms per area of land in an ecosystem. Higher population density could have greater impacts on a population that the actual population size. Therefore, there is an importance in predicting competition in population size. Scientists attempt to predict

If these factors were not analyzed, it would be possible for populations to become extinct. In the predictions of populations sizes, the study of populations over particular regions is needed to determine the resources required to fulfill the needs of the population (Daempfle, 2016). When determining resources, one should consider food, water, shelter, etc. In order for populations to thrive, they should be scattered equally in a region. Whether a population grows or shrinks depends on certain factors such as births, deaths, immigrants, and emigrants. Births are simply new born organisms. Deaths are organisms which have dies and left the region permanently. Immigrants are new organisms that have come area from another. Emigrants are organisms that are leaving an area. Population growth happens when more organisms are entering an area than are leaving. In cases, predators and lack of resources result in the decrease in the size of a population. If it were not for predators, populations would overproduce. Overproduction is dangerous for a population. In every population, there is a carrying capacity. A carrying capacity is the amount of population that an area can sustain in
