"live in" refers to "the place where animals live", followed by the object. (live in does the fixed fiber of place, constituting a verb-object relationship with branches; ）

Example sentence comparison: zoos are terrible places for animals to liveTranslation: A zoo is a place where animals live in a terrible place.

one that was suitable for animals to live in.Translated: zoo suitable for animals.

the city that i live in is very quiet.

The differences between the two are:

Live is an intransitive verb when it means "to live", and it cannot be directly connected to the object, but it is OK after adding the preposition in.
