An organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. What kingdom does it belong in?
• Animalia
• Protista
• Plantae
•Eubacteria

The correct answer is - Eubacteria.

Explanation:

Eubacteria is a kingdom that comes under prokaryotic organisms. These organisms have many characteristic features that are as follows:

Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.

Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.

Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.
