Grasslands never have trees.
Please select the best answer from the choices provided: a) True b) False
The Correct Answer and Explanation is :
The correct answer is b) False.
Grasslands are characterized primarily by their dominant vegetation, which includes grasses and few trees or shrubs. However, it is not accurate to say that grasslands never have trees. In fact, various types of grasslands can feature trees, though in limited numbers and specific circumstances.
For instance, there are two main types of grasslands: temperate grasslands and tropical grasslands (savannas). In temperate grasslands, such as the prairies of North America, trees are generally scarce due to factors like fire, drought, and grazing by herbivores, which prevent tree establishment. However, isolated trees or small clusters of trees can occur, particularly near water sources or in areas protected from grazing.
In contrast, tropical grasslands, or savannas, are characterized by a mix of grassland and scattered trees. These trees are adapted to the environment, often having deep root systems that allow them to access water during dry periods. Species such as acacias and baobabs are commonly found in savanna ecosystems. The presence of trees in these ecosystems is vital as they provide shade, food, and habitat for various species, including birds and mammals.
Furthermore, human activities, such as agriculture and urban development, can influence tree populations in grasslands. Practices like reforestation and agroforestry can introduce more trees into grassland areas, demonstrating that grasslands can coexist with trees under certain conditions.
In summary, while grasslands are predominantly treeless landscapes, it is incorrect to claim that they never have trees. Various factors can lead to the presence of trees in grassland ecosystems, showcasing the complexity and diversity of these environments.
