Questions: Both halotolerant microbes and halophiles require elevated concentrations of NaCl for growth.

The answer is False.

Explanation:

• Halotolerant microbes are capable of surviving and growing in environments with high salt concentrations, but they do not require elevated concentrations of NaCl for growth. They can grow in both low and high salt conditions.
• Halophiles, on the other hand, require high concentrations of NaCl for optimal growth. They thrive in environments with high salt concentrations and often cannot grow well in low-salt conditions.

Therefore, the statement that both halotolerant microbes and halophiles require elevated concentrations of NaCl for growth is incorrect.
