Question

fall final exam (2025 - m)
bacteria that do not need oxygen.
abiotic
aerobic
anerobic

Explanation:

To solve this, we analyze each option:

• Abiotic refers to non - living components of an ecosystem, so it's not related to bacteria's oxygen requirement.
• Aerobic bacteria require oxygen to survive.
• Anaerobic (spelled as "anerobic" in the option, likely a typo) bacteria do not need oxygen to survive. So the correct option is the one with "anerobic" (correct term is anaerobic).

Answer:

C. anerobic (Note: The correct spelling is "anaerobic", but based on the given options, this is the one that represents bacteria not needing oxygen)
