How do ecologists measure the number of organisms in an area? - Answers

Ecologists measure the number of organisms in an area using various methods, including direct counts, sampling techniques, and mark-recapture studies. Direct counts involve physically counting individuals in small, manageable areas, while sampling techniques, like quadrats or transects, estimate population density by examining representative sections. Mark-recapture methods involve capturing, marking, and releasing individuals, then recapturing them later to estimate total population size based on the proportion of marked to unmarked individuals. These methods help provide insight into biodiversity and ecosystem health.
