Answer:
Option (4)
Explanation:
The cloud forests are located at high elevated areas in the tropical and subtropical regions. They are characterized by the presence of clouds that maintains a relatively cold environment, favoring the existence of various type of plant and animal species. The temperature is comparatively low, rich in moisture content and the amount of sunlight also is low in this region. The change in these factors can cause a decrease in the population growth in these cloud forests.
Thus, low moisture content in the atmosphere and excessive amount of sunlight in this type of forest can lead to the reduction in its population.
Hence, the correct answer is option (4).
