An ecosystem is usually defined as a community of living species that exists and interacts with the environment. It is comprised of the producers, consumers as well as the decomposers, where the energy is being carried from one trophic level to the next higher trophic.
When one part of an ecosystem is damaged or destroyed, then it directly affects the remaining parts, and results in the collapsing of the ecosystem. It is because all the organisms are depending on each other forming a food chain. For example, If a particular species belonging to the producer is destroyed then the consumers are directly affected.
Thus, the ecosystem is very essential and plays an important role and all the organisms are dependent on one another.
