Answer:Carnivores and decomposers
An ecosystem is a community which consists of living and non-living components of the environment. The living components are mainly dependent on non-living components like sunlight, soil, water, atmospheric gases like oxygen, carbon dioxide and other factors.
An ecosystem could probably survive without carnivores and decomposers. Carnivores are organisms that are dependent upon other organisms for their food and energy requirements. These includes animals which kills and eat other animals. Example tiger, lion, fox and others. These organisms will limit the population of other organisms for example herbivores. Therefore, without carnivores the ecosystem will survive.
Decomposers: These are the organisms which feeds upon the dead and decaying parts of plants and animals. These organisms act as garbage management system for the ecosystem. They provide beneficial nutrients to the plants after the decomposition process through soil. But in the absence of these organisms plants can survive. Therefore, an ecosystem can sustain without decomposers.
Explanation:
Thus the answer would be Carnivores and decomposers
