Unseen Passage for Class 7 - Passage 20
Posted by Olympiad Tester on
In the heart of the Amazon rainforest, an extraordinary phenomenon unfolds every year known as the "Green Symphony." This natural orchestra involves a synchronized display of vibrant green hues as trees and plants collectively undergo a process known as leaf flush. The synchronized emergence of new leaves creates a breathtaking spectacle that scientists are eager to understand and appreciate.
Researchers have discovered that the Green Symphony is a result of various environmental cues, including changes in temperature, sunlight duration, and rainfall patterns. These factors trigger the simultaneous growth of new leaves across diverse plant species, creating a visual symphony of rejuvenation in the rainforest canopy.
The significance of the Green Symphony goes beyond its aesthetic appeal. The synchronized leaf flush is believed to enhance the rainforest ecosystem's resilience by optimizing the utilization of sunlight and nutrient cycling. This phenomenon also plays a vital role in supporting the diverse array of wildlife that depends on the rainforest for survival.
