Explanation:

Savannas have a distinct wet - dry season pattern. They experience a period of heavy rain followed by a dry season with little rainfall. Grasslands may also have seasonal precipitation, but the wet - dry contrast in savannas is more pronounced. Annual precipitation in savannas is generally higher than some grasslands. Both have grazers, and savannas typically have higher average annual temperatures.
