45. What amount of rainfall does an area typically receive to support grasslands and shrubs kind of vegetation?
[A] Less than 25 cm
[B] Between 25 cm and 75 cm
[C] Between 75 cm to 150 cm
[D] More than 150 cm

Correct Answer: B [Between 25 cm and 75 cm]
Notes:
Grasslands and shrubs ecosystems typically flourish in areas that receive 25 cm to 75 cm of rainfall per year. This range of rainfall is not sufficient for supporting dense forests but is adequate for grasses and shrubs. The richness and distribution of species are greatly affected by rainfall patterns and seasonality. Knowing the amount of rainfall helps in predicting vegetation type in a particular region, which is crucial for management and conservations strategies.
