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

• increases towards the equator

• decreases towards the prime meridian

• decreases in warmer climates

• increases towards the prime meridian

High levels of biodiversity tend to

• have little or no effect on ecosystems

• decrease an ecosystem's resistance to change

• increase the stability of an ecosystem

• make an ecosystem less resilient
