Answer:
Animalia have complex organ systems and Fungi do not.
Explanation:
Fungi are heterotrophic organisms with the chitinous cell wall. The fungal body is made of thread-like long structures called hyphae. Many hyphae together make an entangled structure called mycelium. Hence, fungi exhibit tissue level of body organization.
On the other hand, animals are heterotrophic organisms with no cell wall around their cells. They exhibit organ system level of body organization, that is to say, that they have various organ systems in their body to perform different functions.
