Question

The flow of nutrients in an ecosysten is considered to be a "one way transport.​

Answer 1

Though the energy flow in an ecosystem is one way, the flow of nutrients is cyclical. Known as bio-geo-chemical cycle, the cyclical flow of nutrients required for the organisms to grow are continuously transmitted from abiotic to biotic factors and biotic to abiotic factors within an ecosystem. This cycle functions continuously via a medium of the biosphere that is made up of the lithosphere, atmosphere and hydrosphere.
