The table below shows leaf morphological data for three plant species in a tropical forest ecosystem:
| Species | Leaf dry mass (g) | Leaf surface area (cm2\text{cm}^2cm2) | Leaf dry mass : leaf surface area ratio |
|---|---|---|---|
| Brazil Nut Tree | 4.5 | 225 | 1:50 |
| Hart's Tongue Fern | 0.8 | 320 | |
| Epiphytic Orchid | 1.2 | 12 | 1:10 |
Calculate the leaf dry mass : leaf surface area ratio for the Hart's Tongue Fern. Give your answer in the form 1:N1:N1:N.
Hart's Tongue Ferns are understory plants that grow on the shaded forest floor. Explain how their leaf dry mass : leaf surface area ratio makes them adapted to survive in low-light environments.
