Explain the roles each kingdom plays in an ecosystem and its importance to the sustainability of that ecosystem.

1. Monera - includes bacteria that plays several roles like nitrogen fixation.

2. Protista - produce more oxygen as compared to all land plants put together.

3. Fungi  - fungi degrades organic matter and recycle nutrients in the ecosystem.

4. Plantae - plants carry out the process of photosynthesis and maintains the CO2 and O2 level of the atmosphere.

5. Animalia - animals play a key role in stabilizing the food chain of the ecosystem.
