Respuesta :
Periodic drought and fires are significant factors that help to perpetuate temperate grasslands, such as the American prairies, and prevent them from becoming woodlands. So option c is correct.
Drought and fires both have the effect of reducing the amount of available moisture in the area which reduces the ability of trees to take root and survive. Trees require more water than grasses and are thus much less able to survive in areas that are prone to drought or fire. The lack of trees, in turn, allows for more sunlight to reach the ground and for more grasses to grow, further preventing the area from becoming a woodland. In addition, periodic drought and fires also help to reduce the amount of nutrients available to the soil, making it difficult for trees to thrive in the environment.
The other factors that help to perpetuate temperate grasslands and prevent them from becoming woodlands include mild winters with very little rain, and poor soil. Mild winters with very little rain reduce the amount of moisture available in the environment, making it difficult for trees to take root and survive. Poor soil also prevents trees from taking root, as it lacks the nutrients that are necessary for tree growth. Finally, large numbers of cacti can also help to prevent an area from becoming a woodland, as they are able to thrive in areas that are prone to drought or fire. Cacti are also able to store water and can survive in areas with poor soil, further preventing an area from becoming a woodland.
