is a group of individuals that belong to the same species that live in a particular area at a particular time?
population
are organisms or an individual organism that can interbreed with its own kind?
species
refers to the pattern of spacing among individuals within the population boundary?
population dispersion
is the physical area that defines a population?
population boundary
Patterns of dispersion within a population boundary can be?
clumped, uniform, random
is used to study the population size and density of plants and sessile animals?
Quadrat method
Population density formula?
Population size within the quadrat / Size of the quadrat
Mark-recapture method is used to study the population size of mobile organisms
The method involves capturing a sample, marking individuals, releasing them back, recapturing a new sample, and calculating the population size based on the ratio of marked and unmarked individuals?
