Explanation of Solution
The features that characterize animals are -
- Heterotrophic nutrition - no animal can make its own food; they need to acquire nutrition by consuming other organisms.
- Multicellular, eukaryotic body - all animals are multicellular, even if the cells are not organized into organs.
- Locomotion - most animals move at some point in their life, at least during the larval stages.
Conclusion
Heterotrophic nutrition, multicellular body and locomotion are the three defining characteristics of animals.
