Question

What are examples of population?

Answer 1

A population is defined as the number of natural entities of the same species that live in the same geographic territory at the same time and are capable of interbreeding. Individuals must be able to mate with another member of a population and produce a large number of offspring for interbreeding to occur.

Complete answer:
Examples of population:
1. African Elephants
Although ongoing research has split the African elephants into two species: African bramble elephants and African backwoods elephants, there are two commonly perceived forms of elephants: African elephants and Asian elephants. African elephant populations on the continent are thought to have numbered up to 5 million by people in the mid-1900s. Nonetheless, elephant numbers have plummeted as a result of habitat destruction and poaching for their tusks. There are currently estimated to be approximately 400,000 surplus African elephants.
Despite the fact that when elephant families come into contact, they can cling to form larger gatherings – called 'groups' – of up to 100 people, the elephant group structure is framed by nuclear families of about ten people. One of these throngs encircles a local population. Nonetheless, since any individual from any species can mimic a member of another species, the entire population of every African species remembers every single person who has ever lived on the continent.
2. Lake Populations
There may be different populations within a territory; a lake is a small-scale version. Birds, fish, bugs, land and water creatures, and warm-blooded animals such as otters and rodents can find a natural habitat in a lake. Despite the fact that each species receives resources from the lake, their populations are likely to be dependent on the natural environment in particular. Land provides an impenetrable barrier to fish dispersal. Without a way out, a whole population of trout could survive just in the lake and nowhere else.
3. Salmon
Many forms of salmon are anadromous, which means they are born in fresh water and then move to the sea to care for and mature before returning to fresh water to reproduce. Salmon will, in general, return to the waterway where they were born in order to reproduce. Salmon usually do not wander far from their local spawning site due to this strong desire to return home, but the dispersal distance varies greatly depending on the species.
Since most generating sites are separated by land or deep water, each group of salmon brought into the world in a specific producing site constitutes the local population within that site; despite the fact that the conditions within the courses available for dispersal to other locales are certainly possible for the salmon to withstand, they are rarely found to move between loci.
While drifting, salmon come into contact with salmon from other, even very inaccessible, neighbourhoods. While the matching of neighbourhood populations of similar species does not hamper, salmon's propensity to return to their natal stream considerably reduces quality streams between them. In any case, a few of them either decided or blundered by the way, which leads to some stream of quality between the populations.

Note:
Larger populations are generally more resilient to environmental changes than smaller populations. In a large population, genetic mutations that are conducive to and capable of survival and reproduction are more likely to occur in some individuals.
