LIFE SCIENCE

Detailed explanation-1: -The number of individuals present can also affect the viability of plant populations, with small populations having greater risk of extirpation. In general, the extinction probability of a population increases as population size decreases [25, 26].

Detailed explanation-2: -Environmental effects Again, smaller populations are more likely to become extinct due to these environmentally generated population fluctuations than the large populations. The environment can also introduce beneficial traits to a small population that promote its persistence.
