Question

Quizplus · Accepted Answer

The characteristics of a thin, dark green leaf with stoma on the lower surface only suggest that it is adapted for a high-humidity environment, which is likely found in tropical rainforests. The large surface area (10 sq m) also indicates that the plant needs to maximize its ability to capture sunlight for photosynthesis, which is common in rainforest ecosystems. The other options, such as dry and sandy regions or the floor of a deciduous forest, are less likely to support plants with such characteristics.
