explain how microevolution and migration can affect an ecosystem.

Answer

Brief Explanations:

Microevolution involves small - scale genetic changes in populations. These changes can alter the traits of species, affecting their interactions within the ecosystem such as predator - prey relationships or competition for resources. Migration can introduce new individuals into an ecosystem, changing population sizes and potentially bringing in new genetic material. It can also cause local population decreases in the areas of emigration, and may disrupt food webs and other ecological relationships.

Answer:

Microevolution can change species' traits and interactions. Migration can alter population sizes and genetic composition, disrupting ecological relationships.
