Question

what are bacteria called when they consume or feed on organic matter? carnivores decomposers heterotrophs autotrophs

Explanation:

• Carnivores are organisms that eat other animals, not specifically bacteria feeding on organic matter.
• Decomposers (like many bacteria) break down organic matter, but the term for organisms that consume organic matter (as their carbon source) is heterotrophs. Autotrophs make their own organic matter (e.g., via photosynthesis or chemosynthesis) and do not consume external organic matter. Heterotrophs rely on consuming organic matter (from other organisms) for energy and carbon.

Answer:

B. Decomposers (Note: Also, the more general term for organisms consuming organic matter is heterotrophs, but among the options, Decomposers is the best fit as many bacteria that feed on organic matter are decomposers. If Heterotrophs is an option, it's also correct, but based on typical biology questions, Decomposers is a common answer for bacteria decomposing organic matter. Wait, re - evaluating: The question is about bacteria that feed on organic matter. Heterotrophs are organisms that cannot produce their own food and rely on organic matter. Decomposers are a type of heterotroph that breaks down dead organic matter. So both can be correct, but in the context of bacteria feeding on organic matter, Decomposers is a specific category of heterotrophs that do this. So the correct option is the one labeled "Decomposers" (assuming the second option is Decomposers). So the answer is the option with "Decomposers".
