• D. Natural balance of our environment

Answer 1

Answer: (A)

Natural flora of a place

Green plants are the producers through which inorganic elements first enter the food chain. Green plants take in elements from the atmosphere, soil and water and manufacture food on which all the other animals either directly or indirectly feed on. Since plants are directly exposed to pollutants, the effect of pollution is first visible in natural flora of a place, then it will be visible on organisms that are dependent on the plants.
