Which kingdom would an organism belong to if it were a eukaryotic multicellular heterotroph with chitin in its cell walls?AProtistaBFungiCPlantaeDAnimalia

The organism would belong to Kingdom Fungi. Here's why:

1. Eukaryotic: This term means that the organism's cells have a nucleus enclosed within membranes. Both animals and fungi are eukaryotic, so this doesn't narrow it down much.

2. Multicellular: This means the organism is made up of more than one cell. Again, both animals and fungi are multicellular.

3. Heterotroph: This means the organism gets its food by consuming other organisms. Both animals and fungi are heterotrophs.

4. Chitin in its cell walls: This is the key detail. Animals do not have cell walls, and the cell walls of plants do not contain chitin. However, fungi do have cell walls that contain chitin.

So, the answer is B. Fungi.
