Q. What are the four qualities we use to describe populations?
Demographics can include any statistical factors that influence population growth or decline, but several parameters are particularly important: population size, density, age structure, fecundity (birth rates), mortality (death rates), and sex ratio (Dodge 2006).
Q. What is a main property used to describe a population?

Q. Which of these is not used to describe a population?

Q. What is the most common method used to count a large species population?
Sampling
Q. How do you estimate a species population?
Another efficient method researchers have developed to estimate populations is called “capture-mark-recapture.” Instead of trying to count every animal, biologists randomly capture a sample group of the population, mark it, release it, and then do a series of recaptures that will allow them to estimate the entire …
