The term that encompasses the number of births and deaths, immigration and emigration, along with the influence of biotic (living organisms) and abiotic (non-living environmental factors) factors on populations is best described as "factors that affect populations." This term highlights the various influences on population dynamics, including the interplay of reproduction rates, mortality rates, and movement of individuals in and out of the population, as well as other environmental influences that can impact survival and reproduction.

The other options, while related, do not fully encompass this comprehensive view. Abiotic factors specifically refer to the non-living components of an environment, such as temperature and water, and do not include biotic factors. Biotic factors refer to living components, such as competition and predation, but again do not address the entirety of influences on population dynamics. Carrying capacity refers to the maximum number of individuals that an environment can sustain, which is a specific aspect of population dynamics rather than a general term for all influencing factors.
