Question

1. which type of archaea lives in a high salinity environment?

o methanogens
o halophiles
o acidophiles
o thermophiles

Explanation:

• Methanogens: Produce methane, typically in anaerobic environments like swamps.
• Halophiles: Require high - salt (high salinity) environments to survive.
• Acidophiles: Thrive in acidic environments.
• Thermophiles: Prefer high - temperature environments.

Since the question asks about high - salinity environments, halophiles are the correct answer based on their defined habitat preference.

Answer:

halophiles
