Population Density Changes Over Time — NEET Biology

Which of the above statements are correct? S1: Natality refers to the per capita number of births in a population during a specific time period. S2: Population density at time (t+1) can be precisely represented as N(t+1) = N(t) + [(Births + Emigration) – (Deaths + Immigration)]. S3: Immigration becomes a more significant factor for population growth than birth rates when a new habitat is being colonised. S4: Mortality contributes to an increase in population density, while emigration causes a decrease. S5: For certain ecological investigations, relative population densities, such as the number of fish caught per trap, serve the purpose equally well. S6: Population ecology serves as an important area linking ecology to population genetics and evolution.
