Explain how microevolution and migration can affect an ecosystem.

Sagot :

Final answer:

Microevolution and migration impact ecosystems by altering gene frequencies, genetic diversity, and adaptations within populations.


Explanation:

Microevolution involves changes in allele frequencies within a population over a short period of time, while migration can introduce new alleles into a population or move existing alleles out of a population, affecting gene flow. These processes can impact an ecosystem by influencing the genetic diversity and adaptations of species within it, leading to changes in population sizes and dynamics. For example, if individuals with advantageous traits migrate into a population, they can introduce beneficial genetic variations that enhance the population's ability to adapt to environmental changes.
