"The process by which a species or an organism steadily improves its acclimation to its environment is defined as adaptation." The behavioral or physical characteristics of an animal that improve its ability to thrive in its ecosystem are referred to as adaptation.

Animals can save themselves from predators and extreme weather by adapting.  various birds may conceal themselves under long grass, while weeds, insects, and other creatures can change their color to blend in. Predators find it difficult to locate them in search of food a result.
