How are tropical plants such as bromeliads adapted to the biome in which they live?
They grow from tree branches rather than the forest floor, which helps them to absorb more sunlight.
They have long, thick roots, which helps them to gather the nutrients that are found deep within the soil.
They have hollow leaves and stems for storing water, which helps them to survive long periods with little rainfall.
They lose their leaves during the winter, which helps them to save energy when the temperature falls and prevents the buildup of snow.
