How can the mark and recapture method help ecologists monitor the size of a population?
by mark tag it
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.
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.
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.

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.
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.
What are three ways in which ecologists can estimate the size of a population?
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.

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.
