Final answer:
Trees in a tropical rainforest possess buttress roots as a support system due to the unique environment they grow in, including shallow and nutrient-poor soil, heavy rainfall, and strong winds. Buttress roots provide stability, prevent toppling over, absorb water and nutrients, and help prevent soil erosion.
Step-by-step explanation:
Trees in a tropical rainforest possess buttress roots due to the unique environment they grow in. Buttress roots serve as a support system for the tall, towering trees, which can reach great heights in the rainforest. The shallow and nutrient-poor soil in rainforests can make it difficult for trees to anchor themselves, especially when faced with heavy rainfall and strong winds.
Buttress roots are wide and flared structures that emerge above the ground and extend from the base of the tree trunk. These roots provide additional stability and prevent the trees from toppling over. They spread out horizontally and can reach far distances, maximizing contact with the soil to absorb water and nutrients.
Furthermore, the buttress roots also help to prevent soil erosion. The root system spreads out like a broad network, reinforcing the soil structure and reducing the risk of erosion caused by heavy rainfall.
