Q1382. Consider the following statements regarding the layered structure of tropical rainforests: I. The emergent layer consists of the tallest trees that rise above the general canopy and receive maximum sunlight. II. The understory layer is densely packed with vegetation because it receives an abundance of direct sunlight. III. The forest floor is generally dark, receiving less than two percent of sunlight, limiting plant growth mainly to fungi and decaying matter. Which of the above statement(s) is/are correct?
Explanation
Tropical rainforests possess a complex vertical stratification consisting of several distinct layers. The emergent layer contains the tallest trees rising above the canopy to capture maximum sunlight. Conversely, the forest floor receives very little light, which severely restricts the growth of green plants. The understory remains relatively dark and humid, supporting only those species specifically adapted to low-light forest environments.

While this organization plays a vital role in national security by advising the government on military logistics and equipment, its primary focus is on defense technology.

RAS PrelimsWorld Geography · Natural Vegetation and Biomes
Q1387. Plants in the desert biome exhibit various xerophytic adaptations to survive arid conditions. Which of the following is not a recognized adaptation of desert vegetation?
Explanation
Xerophytic plants employ various specialized strategies to minimize water loss and maximize moisture retention in arid environments. Common adaptations include deep taproots, waxy leaf coatings, and succulent stems for water storage. However, broad and thin leaves are avoided because they would significantly increase transpiration rates. Instead, desert plants often reduce leaf surface area or transform leaves into sharp spines.

Q1388. Identify the odd one out among the following instruments of economic stabilization.
Explanation
Economic stabilization measures are generally divided into monetary and fiscal categories. Tools such as open market operations, statutory liquidity ratios, and standing facilities are managed by the central bank to regulate money supply and interest rates. In contrast, taxation strategies involve government decisions regarding revenue collection, representing a primary instrument of fiscal policy rather than central bank operations or tools.
