I understand kacza to zwierze being right but how is "kaczka jest zwierzeciem" also right? Isn't that 'a duck is animals'?

In a lot of cases, they're completely interchangeable. Have a look here: https://www.duolingo.com/comment/16373167

Zwierz takes irregular form in the Instrumental case - you should add -ęc-

The explanation Tadjanow and MariZahariev gave is interesting, but I don't find it very helpful. Why do we use the instrumental case when we categorize things?

Often there's no better answer than "we just do". At least unless someone is educated in the history of language...

The option to choose "to" is not available in this sample.

If "Kaczka jest zwierzęciem" was available, and I guess it was, then everything is fine. Well, could be better (see here: https://forum.duolingo.com/comment/27952965), but it's fine.
