B
Savannas are typically found in colder climates than temperate grasslands.
C
Savannas have a higher density of trees compared to temperate grasslands.
D

Verified step by step guidance1
Begin by understanding the definitions of savannas and temperate grasslands. Savannas are grasslands with scattered trees, typically found in regions with seasonal rainfall. Temperate grasslands are areas dominated by grasses, with few trees, and experience moderate rainfall.
Consider the climate differences between the two biomes. Savannas are usually found in tropical or subtropical regions, which are warmer, while temperate grasslands are found in regions with more moderate temperatures.
Examine the vegetation structure. Savannas have a higher density of trees compared to temperate grasslands, which are primarily composed of grasses with few trees.
Analyze the biodiversity aspect. Temperate grasslands often have a greater diversity of large herbivores due to the extensive grass cover that supports grazing animals.
Conclude by comparing the rainfall patterns. Temperate grasslands generally receive more annual rainfall than savannas, which have distinct wet and dry seasons.
