Environmental Final Exam Review

The latitudinal gradient is a natural pattern in which species diversity generally

• increases toward the poles.

• increases toward the equator.

• increases toward the prime meridian.

• decreases in warmer climates.

High levels of biodiversity tend to

• have little or no effect on ecosystems.

• decrease an ecosystem's resistance.

• make an ecosystem less resilient.

• increase the stability of an ecosystem.
