The first way an Ecologist can estimate a population is to use, trap, check ,release. Another way is that lets say a ecologists counts 100 goats in 1 acre out of 100 acres. He then multiplies the number inside 1 acre with the total amount of acres.

∙ 10y agoThree 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 for rabbits. 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.
Hope that helps.

Why do ecologists use the technique of sampling to estimate population size?
In many cases, it is not even possible to count signs of every member of a population. The population may be very large or spread over a wide area. In such cases ecologists usually make an estimate. An estimate is an approximation of number, based on reasonable assumptions.
How can the mark and recapture method help ecologists monitor the size of a population?
by mark tag it
Why do ecologists start quadrat vegetation analysis by constructing a species-area curve?
Plant ecologists often used the species-area curve to estimate the minimum size of a quadrat necessary to adequately characterize a community
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.
Why do ecologists study the biosphere?
Population ecologists study the size, density, and structure of populations and how they change over time. ... Ecologists working at the biosphere level may study global patterns—for example, climate or species distribution—interactions among ecosystems, and phenomena that affect the entire globe, such as climate change.
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

Why is it difficult to estimate the size of a population of animals?
They never fill out the census forms.
What is the population of Fiji?
The 2007 census estimate of Fiji's population was 837,271. There are three-hundred islands in Fiji. These islands range in size from small coral atolls to large volcanic islands. Only about 100 of the islands are inhabited.About 945,000.
