Answer: The correct answer is C) Community stability.

  • In the given question, some micro-organisms survive in the digestive tract of the cattle.
  • These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
  • On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.
