by using the capture-recapture method which gives you the total size of organisms in a 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.
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.

what are the steps involved in the mark and re-capture method in population sampling
It's called "Reconquista". Capture of Aztec empire was conquista, so from this we have "conquistadors".

Direct observation: Counting individuals in the population through visual or physical assessment. Mark and recapture: Capturing and marking individuals, releasing them back into the population, then recapturing to calculate population size based on marked individuals. Transect sampling: Counting individuals along predetermined transects or lines within the population. Remote sensing: Using satellite imagery or other technology to estimate population size based on habitat characteristics.

leafy seadragons only live in south australia and the population counted with the capture/ recapture method is 1,527,400
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.
The assumptions of the mark-recapture method include: 1) The population is closed (no immigration, emigration, or deaths) during the study period, 2) Marks do not affect the probability of capture, and 3) Marks are not lost or overlooked between captures.
Census taking for sea horses is an impossible task. The best that you can hope for is a capture-recapture exercise.
Deer and other animals that do not stay put. Squirrels, salmon, and butterflies are some other examples.
Four ways to determine population size include conducting a census, using statistical sampling methods, employing satellite imagery and remote sensing, and analyzing demographic data. Each method has its own advantages and limitations depending on the population size and distribution.
