Answer:
It should be classified in the animal kingdom.
Step-by-step explanation:
This organism should be in the animal kingdom classification. Why? Well, in the text it gives us a big clue: "eats food for energy." Plants use the sun for their energy, and make their own food (photosynthesis). But, animals on the other hand do eat food for energy. There is no way that this organism is a plant if it eats food for energy. The other researcher who thinks it is a plant probably thought so because this organism is green, and probably thought "Oh! Chlorophyll must have caused the green color" (Chlorophyll/green color in plants is a PLANT characteristic), but this researcher was wrong and the green color was not caused by chlorophyll.
