or very hot places. these organisms are called _.
extremophiles
stromalites
cyanobacteria
phototrophs

Explanation:

• Extremophiles: Organisms that thrive in extreme environments (e.g., high/low temperature, salinity, pH).
• Stromatolites: Layered structures formed by microbial mats (usually cyanobacteria), not about living in extremes.
• Cyanobacteria: Photosynthetic bacteria, not specifically defined by extreme habitats.
• Phototrophs: Organisms that use light for energy, not tied to extreme conditions.

Answer:

extremophiles
