How does the way matter flows through an ecosystem differ from the way that energy flows?
-Energy is passed in one-way direction through the biotic (living organisms) in an ecosystem
- Matter cycles within and between biotic and abiotic parts of an ecosystem.
Process in which bacteria convert nitrates into nitrogen gas and release it into the atmosphere

Autotrophs or producers
Why is only about 10% of the energy in an organism transferred in a food chain?
