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?
Hio
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.
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 one method the ecologists use to estimate the size of a population?
survey
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 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 does the number of individuals in a population that occupies an area of a specific size describe?
Spacing
What does the number of individuals in a population occupying in area of a specific size describe?
I believe you're referring to population density.

Why is it difficult to estimate the size of a population of animals?
They never fill out the census forms.
