Architect of Nature — EVS STD 5 — Question

The departure of turtles, snakes and lizards from the forest, caused a serious environmental imbalance. When the turtle left, the forest began to smell of rotten fruits and dead fishes. Without snakes, the number of rats increased, which started harming crops and grains. In the absence of lizards, the population of insects and frogs became uncontrolled. As a result, there was diseases and disuption of the food chain in the forest which affected the entire ecosystem.
