Thirdly, you can never, ever, ever get the exact population because every second a baby is born, adding to the population. Hope this helps! Caeleen

What factors determine a population size?

Why do scientists need to know the size of a population?
Sometimes they do, sometimes they don't.
What is the number of individuals in a population called?
The number of individuals in the population is the population's size. If a population is small enough you will be able to determine the size by counting the individuals.
What is the survey used to determine population size called?
A census.
Why is it difficult to estimate the size of a population of animals?
They never fill out the census forms.
What is the direct population size of the chinchillidae?
The direct population size of the Chinchillidae family, which includes chinchillas, is difficult to determine as it varies depending on the specific species and their natural habitats. While some species have larger populations, others are endangered or critically endangered with smaller numbers. For example, the critically endangered Chilean chinchilla has an estimated population of only a few thousand individuals.
What determine the kind and size of population in the area?
How many of the same types of organisms live in that area .
How can an ecologist ecologist measure population size?
Ecologists can estimate population size through methods such as mark-recapture, distance sampling, and census surveys. Mark-recapture involves capturing and marking individuals, releasing them, and then recapturing a sample to estimate total population size. Distance sampling involves estimating population size by observing and recording the distances to individuals from a specific vantage point. Census surveys involve conducting a thorough count of all individuals in a specific area.
What is the most least invasive way to determine population size?
The least invasive way to determine population size is to use the sampling technique. If you are able to determine how many subjects are in a few small areas, you may be able to estimate how many are in the entire area. An example would be, if there are 10 people living in one apartment building, and there are a total of 50 apartment buildings in the complex, an estimate of your population size would be 500, assuming there are no empty apartments.
Why do smaller populations need larger sample sizes?
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.
Who is the worlds biggest spender?
On a personal level, it is difficult to determine a single individual as the world's biggest spender. However, countries like the United States tend to have higher levels of consumer spending overall due to the size and wealth of their population.
What kind of evidence is used to determine the relationships between animals?
Everything from where they live to body structure. Sometimes even size.
