Which of the following characteristics is NOT typically found in grasslands?

Grasslands are ecosystems primarily characterized by the dominance of grasses, which thrive in regions with moderate rainfall and an absence of significant woody plants. The presence of woody vegetation is uncommon in grassland areas, as these ecosystems generally have insufficient moisture to support the growth of trees and shrubs. Grasslands are adapted to disturbances such as grazing and fire, which prevent the encroachment of woody species.

In terms of biodiversity, grasslands often feature a diverse array of forbs—herbaceous flowering plants that contribute to the overall ecological richness. Additionally, grasslands are noted for their high carbon sequestration capacity due to the extensive root systems of grasses, which help store carbon in the soil.

By understanding these defining characteristics, it's clear that the absence of woody vegetation is a key trait of grasslands. This juxtaposition is what makes the presence of such vegetation in grasslands incorrect.
