There is no sampling method that will select the exact population.
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.
By taking a sample of the entire population.

There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
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 basic methods used by ecologists to study the living world include experimenting, classifying, and modelling, but not observing.
Yes, ecologists often use a combination of descriptive and quantitative methods in their research. Descriptive methods provide detailed observations and background information, while quantitative methods involve collecting numerical data and statistical analysis to test hypotheses and quantify relationships in ecological systems. The integration of both approaches helps ecologists gain a comprehensive understanding of the natural world.
