  • In a balanced condition, ecosystem functioning is self- regulating and self-sustaining.
  • This dynamic nature of the ecosystem is dependent upon a number of factors including the flow of energy and cycling of materials.
  • This is possible because of the constant interaction between different biotic and abiotic components of the ecosystem.
  • Plants, animals, and microbes are interdependent.
  • This makes the ecosystem self-regulating and self-sustaining with all the components of the ecosystem.
  • So, the correct answer is option A. Both assertion and reason are true and reason is the correct explanation of assertion.
