Is the word organizam the same in Brazilian and European Portuguese?

Yes.

The spelling, meaning, and grammatical function of "organizam" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels undergo significant reduction; for example, the initial "o" often sounds more like a "u," and the final "a" is much more closed or nearly swallowed.
