- The emergent layer is primarily composed of small leaves that cover a wide area, while the understory layer is primarily composed of
broad leaves that cover a small area. This difference is most likely because the average precipitation at heights of:
A. 0 to 30 m above the rainforest floor is above 2.00 mm/km^2 /yr, whereas the average precipitation at heights of 30–45 m above the
rainforest floor is below 0.33 mm/km^2 /yr.
B. 0 to 30 m above the rainforest floor is above 2.00 mm/km^2 /yr, whereas the average precipitation at heights of 45–55 m above the
rainforest floor is below 0.33 mm/km^2 /yr.
C. 0 to 30 m above the rainforest floor is below 0.33 mm/km^2 /yr, whereas the average precipitation at heights of 30–45 m above the
rainforest floor is above 2.00 mm/km^2 /yr.
D. 0 to 30 m above the rainforest floor is below 2.00 mm/km^2 /yr, whereas the average precipitation at heights of 45–55 m above the
rainforest floor is above 1.33 mm/km^2 /yr.
