The two primary factors that determine a population's size are the availability of food, and the prevalence of predators.
In the abscence of predators, a population will grow until the food it consumes becomes equal to the food that is provided by the ambient ecosystem, available to the relevant population through the food chain. After that, the population cannot grow more unless the ecosytem suddenly is capable of providing more food.
Predators regulate populations as a result of the connection between predators and prey in ecosystems. If there is an increase in the size of the prey population, more food will be available to the predators, so their population will also grow. The increased predator population will put downward pressure on the prey population as the predators feed upon them. If the prey population suffers substantial decreases, the predator population will also suffer knock-on decreases as there will be less food available to them.
Viruses play a role in nature by helping regulate population sizes of host organisms, transferring genetic material between organisms, and influencing ecosystem dynamics through their interactions with other organisms.
Predator-prey cycles in nature include relationships like wolves and deer, or lions and zebras. These cycles impact the ecosystem by regulating population sizes, maintaining biodiversity, and influencing the distribution of species.
The name for the study of changes in the sizes of populations is called demography. It involves analyzing factors such as birth rates, death rates, migration, and age distribution to understand population dynamics and trends.
This could be anything, from earthquakes to migration to floods to disease, and so on, and so forth. In nature, population sizes naturally fluctuate even without such events, due to changes in the availability of resources, predation, and so on.
To calculate the generation time of bacteria, you can divide the total time it takes for a bacterial population to double by the number of generations that occurred during that time. This can be determined by measuring the initial and final population sizes and the time it took for the population to double.
the combination of population sizes that will ultimately result regardless of the initial combination of population sizes.

They don't ... they get smaller with time.
an equilibrium point at which, if either population changes, the population sizes will diverge from, rather than return to, the equilibrium point; a combination of population sizes at which the two populations could coexist, but when the combination changed, no impetus exists to return to the equilibrium population sizes.
The global snake population is not precisely known due to their elusive nature and wide distribution. Estimates suggest that there are thousands of snake species worldwide, with varying population sizes depending on species and habitat. Conservation efforts are important to ensure the protection and sustainability of snake populations.
