There are many methods worth mentioning including:
Sampling: Count a small part and assume even distribution.
Differential equations: Can take into account the ammount of food available, predetor populations and disease among other factors.
Census: Sit down and count one by one.

How can an ecologist ecologist measure population size?
An ecologist can determine the size of a population without counting every organism by either sampling, mark-and-recapture studies, or indirect or direct observation.
How can an ecologist predict the size of a population?

What is capture mark and release method?
Mark and recapture is a method commonly used in ecology to estimate an animal population's size where it is impractical to count every individual. A portion of the population is captured, marked, and released.
When can you estimate a population's size when counting individuals in a sample of the population?
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
Describe 3 ways in which ecologist can estimate the size of a population?
Three ways ecologist can estimate the size of a population is by trap-mark-release methods,sample counts and evaluating the resource in the area . The trap-mark and release method works by setting unharmful traps for the animals of your choice. Each animal that you are looking for are marked and then released. Later , more animals you are looking for are captured. Some animals will have marks, many will not. By analyzing these samples, ecologists can estimate the size of the population. The sample count involves using a large area to count animals. Say, if there is a 100- acre area, filled with animals of the same kind. Take one acre and count the animals. Then multiply that number by 100 to equal a rough estimate of the population. The resources in the area can provide valuable information. Say, you mwere looking forrabbits. it is a fairly small area, of about 1 sq. mile. The is not a lot of resources and plenty of natural predators. You can naturally assume about 20 or so rabbits living in the area.
How can an ecologist predict the size of a population without counting every organism in the population?
Through mark-and-recapture projects, direct observations, or targeted sampling, ecologists are able to determine the population of a particular species. This process is a scientific estimation of the population.
What is the estimate current world population size?
4.3 billion
What is the formula to calculate size of a sample?
by using the capture-recapture method which gives you the total size of organisms in a population.
Why is it difficult to estimate the size of a population of animals?
They never fill out the census forms.
How can the mark and recapture method help ecologists monitor the size of a population?
by mark tag it
