AURORKA [14]

Answer:

The given blank can be filled with minimum viable population.

The MVP or the minimum viable population refers to the lowest number of individuals or the minimum density of the population of a species that can thrive in a specific region. The term is generally used in the fields of ecology, biology, and conservation biology.

The minimum viable population refers to the smallest probable size at which the population can prevail without encountering extinction due to demographic or natural disasters, genetic, or environmental stochasticity. Generally, MVP is utilized to signify towards a wild population, however, it can also be utilized for ex-situ conservation.
