Answer:
The Bi-diversity provides "raw materials" for the food chain and seafood production, and also influences the capacity of ecosystems to perform these and other services. Therefore if the organism is removed from the food web, It will spoil the flow of energy in the ecosystem.
Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms. nutrients are taken up by plants through their roots. nutrients pass to primary consumers when they eat the plants.
