When two populations do not reproduce, it is referred to as reproductive isolation. This phenomenon can occur due to various barriers, which may be prezygotic (preventing mating or fertilization) or postzygotic (affecting the viability or fertility of offspring). Reproductive isolation is crucial for the process of speciation, as it leads to the divergence of populations into distinct species.
isolation
The border across which genes can flow between two populations is called a "gene flow barrier." This barrier can be physical, such as a mountain range or river, or it can be due to behavioral or ecological factors that limit gene exchange between populations.
When individuals in a population reproduce at a constant rate, it is called an exponential growth. Populations generally experience this growth under ideal conditions.
This could be referred to as "sexual reproduction."
In biology, fission is the subdivision of a cell (or body, population, or species) into two or more parts and the regeneration of those parts into separate cells (bodies, populations, or species).Binary fission produces two separate cells, populations, species, etc.Bacteria is a prokaryote. Prokaryotes do reproduce asexually through binary fission.So binary fission is the means by which bacteria reproduce.
When two or more populations live together, it is called a community. In ecology, a community refers to a group of interacting species living in the same area.
Yes, a community can have two or more populations of the same species coexisting together. This can happen if different populations occupy different niches within the community, leading to their coexistence. Additionally, variability in factors like food availability, habitat preferences, or behavior can also allow multiple populations of the same species to inhabit a community.

Invasive species
Temporal Isolation
They become separate species.
When the two populations can no longer interbreed.
