What primary characteristic places H. nasicus in Kingdom Animalia instead of the Plant Kingdom?

Answer

It is a heterotrophic organism

The placement of *H. nasicus* in the Kingdom Animalia signifies a fundamental difference in how it acquires energy compared to organisms in the Plant Kingdom. Animals are classified as heterotrophic, meaning they cannot synthesize their own sustenance via processes like photosynthesis, which is characteristic of plants. Instead, members of Animalia, from the smallest invertebrate to the largest mammal, must actively consume and digest other organisms—whether plants or other animals—to meet their energy requirements. This defining characteristic of nutrient acquisition is the basis for its placement at the highest taxonomic level provided.
