The correct answer is 1 and 4. ExplanationLianas (woody vines) have unique physiological and structural adaptations that distinguish their distribution patterns from those of most tropical trees.Statement 1 (Negative relationship with mean annual precipitation): Unlike trees, which generally increase in biomass and density as rainfall increases, liana density tends to decrease in extremely wet forests. In areas with very high annual rainfall, lianas are often outcompeted by the dense, fast-growing canopy of trees.Statement 4 (Positive relationship with the length of the dry season): Lianas are highly efficient at transporting water and maintaining growth during dry periods. They have deep root systems and efficient vascular systems that allow them to thrive when trees might go dormant or struggle. Therefore, as the length of the dry season increases, the relative density and competitive advantage of lianas over trees also increase.
