Study Notes
Survival in Dark Environments
- The most crucial adaptation for survival in a dark environment is the development of sensory organs that do not rely on light, such as lateral lines or electroreception.
- The primary challenge for an organism in a dark environment is the inability to detect food, predators, or obstacles through vision.
Survival in Extreme Environments
- In extreme environments, the most critical factor for an organism's survival is its ability to adapt to the specific conditions, such as high pressure, temperature, or salinity.
- Organisms must develop specialized physical and physiological features to survive in extreme environments, such as deep-sea fish with large eyes or thermophilic microorganisms that thrive in hot temperatures.
