I have been advised that I will be soon receiving a gift from my children a D7100! I currently have a D700 which I love and almost all my lens are FX. Will these lenses work on the d7100 ? If not I will try and let them know that maybe a 28- 300 lens would be something I really would like and cost them less cash. Your thoughts ?b Oh I like taking wildlife and nature I.e. mountains natural parks etc.. Just starting to look at buildings and people being themselves candid on the street. Hope the helps?

Just about any Ai-S and later (D, G lenses) will work just fine.
I hate when people ask me what I see myself doing in 5 years...... I don't have 2020 vision!

You don't say which full-frame lenses you have but fortunately the D7100 retains the in-body AF drive so that it will be able to autofocus the older non AF-S lenses that require a mechanical AF linkage. Basically any lens that works on your D700 will also work on the D7100. There will be some differences in usage:
1) Reduced field of view with the DX body. Your focal lengths will all be 1.5x as mentioned above so your wide-angle shooting (architecture, landscapes) may be affected when using the DX body. You didn't say what FX wide angle lenses you have but the ultra-wide FX zoom lenses (e.g. 18-35mm, 17-35mm, 16-35mm 14-24mm) will be only moderately wide on DX format.
2) Improved sharpness across the frame because the DX crop takes the sharper centre portion of the image circle produced by the lens. Sharpness across the frame should be improved.
3) Increased depth of field : the smaller DX format will result in greater depth of field for the same field of view and aperture.
Because of these effects, and assuming you will be keeping your D700 it would be best to use your existing wide angle lenses with the D700 and your longer lenses on the D7100 to maximise the reach advantage when photographing wildlife.

Don't forget that in addition to the 1.5X crop mode everyone is mentioning, the D7100 also has a DX-1.3X crop, which translates to a 2X crop from full frame; your 100mm lens' image is cropped to the FOV of a 200mm lens. Because the D7100 is a 24MP camera, you still end up with a usable image. Your 28-300mm lens (if you had both) would have the same field of view as a 56-600mm FX lens, at reduced resolution.
You can also crop in post, of course, but for sports and other types of subjects it's often more convenient to shoot the frame you actually want to end up with and not have to manually crop later.
