In this tolerance diagram, the optimal or ideal range of conditions is:

• Across the whole chart
• Where the line of the curve is at its highest
• On the far right and left of the bell curve
• There is no way to tell

Which term describes the range of values an organisms can tolerate or withstand in an ecosystem?

• range of tolerance
• optimum zone
• zone of physiological stress
• zone of intolerance

Limiting factors are sometimes helpful because they can keep the population from getting too large.

• True
• False
