What the behavioral adaptations?
Behavioral adaptations are different to physical adaptations because behavioral adaptations are (like the name suggests) changes in behavior that increase an organisms fitness/survival, whereas physical adaptations are changes to an organisms body structures. The two are not exclusive, you can have behavioral AND physical solutions to the same problem. Best illustrated with some examples: heat and heat regulation; if an organism gets too hot it can move out of the sun and into shade, that is a behavioral adaptation. Or, over millions of years it can evolve mechanisms of cooling, humans do it by sweating, dogs pant, birds fluttering their throat muscles (called “gular fluttering” but it is essentially panting!)Another example: deer respond to the presence of a predator by running away, or joining together in groups (herds) – these are changes to its behaviour that decrease its chances of getting eaten. Physical adaptations to not getting eaten would be having highly developed leg muscles for quick acceleration and running away, or maybe camouflage colouration, or confusing colouration (such as the stripes on zebras, which make it hard to see one individual from another when they are in a group)
