Answer 2

There are many food chains which are interconnected to form the food web and so one organism can feed at different trophic levels in the different food chain.

There is a gradual decrease in the energy of the increasing trophic levels due to the loss of energy with each transfer. This is explained by the 10% energy law given by Lindman.

The producers are the organisms which can synthesize food and the organisms which feed on the other sources are known as consumers.

The detritivores are the organisms which feed on the dead matter of the organisms which belong to all the trophic levels.

Thus, the correct answer is option D.
