Question

Do u think there is any limitation regarding the number of trophic level in detritus food chain?

Answer 1

In any kind of food chain, detritus or grazing, number of trophic levels is limited to 4-5 pertaining to the 10% law of energy transfer which states that only 10% of the energy content is passed on to successive levels. After five trophic levels, negligible amount of energy would be transferred to the next level of organisms making it impossible for it to survive. Moreover, detritus food chain starts with decomposing matter which is already low in energy content so these are shorter than grazing food chains.

Answer 2

The detritus food chain is limited in following:

Available solar energy often remains underutilized . decomposition is largely aerobic process , requiring oxygen .It's efficiency is heavily dependent on chemical composition of dead organic matter , environmental , temperature,PH and climatic conditions.
