What is the term for non-domesticated plants and animals in an ecosystem?

The term that refers to non-domesticated plants and animals in an ecosystem is "wildlife." Wildlife encompasses all living organisms that exist in their natural habitats without human intervention, including a wide variety of species of animals, birds, insects, and plants. This term is often used in the context of conservation and ecology to highlight the importance of preserving these species and their habitats for biodiversity.

Natural flora and fauna refer to the same idea but are more descriptive; however, they are not as commonly used in the general context of referring to wild species. Feral life typically describes domesticated species that have returned to a wild state, which does not cover all non-domesticated life forms. Native species denote species that are originally found within a specific region but does not encompass all non-domesticated species, as some wildlife can be non-native. Therefore, "wildlife" is the most encompassing and widely recognized term specifically denoting non-domesticated organisms within ecosystems.
