Question

Quizplus · Accepted Answer

Buttressed bases are common in trees of tropical rain forests because they need structural support to counteract the shallow root systems that they possess. These shallow roots are due to the presence of nutrient-poor soils and high competition for nutrients. The buttresses help to distribute the weight of the tree over a larger surface area and provide additional support.
