Question

The altitudinal gradient describes a pattern where species diversity is greatest at which elevation?

Options

• Mid-range altitudes only

• Altitude does not affect species diversity

• Lower altitudes

• Higher altitudes

Answer 1

The altitudinal gradient is defined as the pattern in which species diversity is greater at lower altitudes and declines with increasing altitude. Mountain slopes demonstrate this pattern, with more diversity at lower elevations than at higher elevations.
