If an isolated population and rsquos birthrate is the same year after year why are a greater number of individuals added to the population in each successive year?

There is a population of fish in an isolated pond what is true of the birthrate and the death rate when the pond reaches its carrying capacityexplain?
they are one and the same
The drastic reduction in genetic variation that results when a new isolated population is established by a very small number of individuals from a larger population is known as?
the founder affect.- got it from SI
How geographic contributes to evolution?
Certain geographic features isolate a small number of individuals from the rest of the poopulation. Variations that are not common with the larger poopulation may become common with the isolated population so that the variations can create new breeds in the isolated part of the population.Therfore, not only can evolution take place in the crowded areas but also in the isolated part of the population.
How does two organism's join a population?
Although the dynamics and evolution of a single closed population are governed by its life history, populations of many species are not completely isolated and are connected by the movement of individuals (immigration and emigration) among them.
Can form when a group of individuals become isolated from the main group?
species
What can form when a group of individuals become isolated from the main group?
Species.
What might cause a population to become isolated?
If the population do not or can not conform to the normalities of that society.
What is it called when a population diverges and becomes reproductively isolated?
Speciation
Why did Ethiopia become increasing isolated over the countries?
Population
Is it true that when some members of a species become isolated they are less likely to form a new species?
Isolation is often the precursor to the generation of a new species or subspecies. Small populations of isolated individuals can go through genetic drift, a condition where a considerable change in the phenotype/genotype of the population occurs in one or two generations. Prolonged isolation could yield substantial change if environmental pressures are different in the isolated region compared to the larger population from which it separated.Snow Leopards are an example of changes in coat thickness, coat color, tail length and fat storage which are adaptations to an alpine environment. Whether the progenitors of the Snow Leopard were isolated from the main population during glaciation, marginalized individuals that migrated where they could fill an unoccupied niche, out competed the previous niche holder or some combinationof these possibilities the result is the Snow Leopard.
What types of population does genetic drift affect?
Isolated populations can lose genetic diversity through genetic drift. This is because some alleles can be lost by chance. Many more homozygous individuals are likely.
What happens to any population when its small and isolated from gene flow?
Mutations
