How does a temperate grassland typically differ from a rainforest biome?

A temperate grassland is fundamentally characterized by its dominance of grasses and the scarcity of trees. This biome typically has a moderate climate with distinct seasons, which influences its vegetation. The conditions of temperate grasslands lead to the evolution of grasses that are well adapted to withstand drought and periodic fires, which help maintain the grassland ecosystem by preventing the encroachment of trees and shrubs.

In contrast, rainforest biomes are defined by their dense tree cover and significantly higher levels of rainfall. Rainforests have a diverse array of plant species and are typically found in regions with warm temperatures year-round, unlike the seasonal variations seen in temperate grasslands. The ecological roles of these two biomes are quite different, with rainforests contributing to higher biodiversity and carbon storage due to their extensive canopies and complex structure.

Thus, the focus on grass dominance with few trees in temperate grasslands is a defining feature that sets it apart from the lush, tree-rich environment of rainforests.
