It starts from the dead organic matter and decomposers called detritivores as the first trophic level.
2.
A much less fraction of energy flows through this type of food chain.
A much larger fraction of energy flows through this type of food chain.
3.
It binds to inorganic nutrients.
It releases the inorganic nutrients bound in organic matter
4.
It is directly dependent on the influx of solar radiation.
Energy for the food chain comes from the organic wastes, exudates and dead matter termed as detritus.
