HETEROTROPHIC
Explanation:
Based on nutrition, organisms are classified into autotrophic and heterotrophic. Autotrophic organisms are organisms that are capable of making their own food using either light source (photosynthesis) e.g plants or chemical source (chemosynthesis) e.g some bacteria.
Contrarily, HETEROTROPHIC organisms are those that are unable to synthesize their own food themselves, hence, they rely on other organisms for their energy source. Types of heterotrophism include; saprophytism, predation etc. Most bacteria falls under this heterotrophic category because they are unable to make their own food.
