Can someone tell me what

this hose is for please? Went out this afternoon and popped the hood on my 2006 Tacoma with the 2tr-fe and found this hose loose. It runs in between the manifold and the little triangle air chamber that sits above the numbers two and three spark plugs. Looks like something had tried to make a nest and knocked it loose. I but it back together and put a hose clamp at the top. Tbh I have no idea how long it was off on one end (not a spot I usually look). My truck seems to be running ok so if anything did get sucked in it must not have been very big. How worried should I be?
