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 is something that can restrict the size of a population?
Limited resources such as food, water, or habitat can restrict the size of a population by creating competition among individuals for these resources. Predation, disease outbreaks, and natural disasters can also play a role in limiting population size by reducing the number of individuals in a population.
What is Population Size limited by?
Population size can be limited by factors such as availability of resources (food, water, shelter), predation, competition for resources, disease, and environmental conditions (such as climate and habitat suitability). These factors can influence birth rates, death rates, and migration patterns within a population, ultimately affecting its overall size.
