Directions For Questions
Direction: Read the given passage carefully and choose the best answer to each question out of the four alternatives.
Men, animals, birds, plants and insects are a link in the great chain of life. They are interdependent for their survival. If they are at peace with one another and their surroundings, they may be said to sustain a state of equilibrium. This, the ecologists say, is conducive to the growth of all species. Population explosion and rapid advances in technology have disrupted this ecological balance. Most vulnerable to these influences are plants whose extinction sets off chain reactions exterminating other species. A knowledge of relations of living organisms to each other and to their surroundings is essential to save the earth from turning it into a lifeless desert
