Solution and Explanation
Step 1: Grazing Food Chain (GFC) begins with green plants (producers) at the first trophic level. Energy is captured from sunlight.
Step 2: Detritus Food Chain (DFC) begins with dead organic matter (detritus). It is made up of decomposers (saprotrophs) like fungi and bacteria.
Step 3: In terrestrial ecosystems, a much larger fraction of energy flows through the DFC than through the GFC.
Step 2: Detritus Food Chain (DFC) begins with dead organic matter (detritus). It is made up of decomposers (saprotrophs) like fungi and bacteria.
Step 3: In terrestrial ecosystems, a much larger fraction of energy flows through the DFC than through the GFC.

- Read the passage carefully and answer the given questions.
Comprehension Passage:
A pond is a shallow water body in which all the basic components of an ecosystem are well exhibited.
The abiotic component is the water with all the dissolved inorganic and organic substances and the rich soil deposit at the bottom of the pond.
The solar input, the cycle of temperature, day-length and other climatic conditions regulate the rate of function of the entire pond.
The autotrophic components include the phytoplankton, some algae and the floating, submerged and marginal plants found at the edges.
The consumers are represented by the zooplankton, the free swimming and bottom dwelling forms.
The decomposers are the fungi, bacteria and flagellates especially abundant in the bottom of the pond.
This system performs all the functions of any ecosystem and of the biosphere as a whole, i.e., conversion of inorganic into organic material with the help of the radiant energy of the sun by the autotrophs, consumption of the autotrophs by heterotrophs, decomposition and mineralisation of the dead matter to release them back for reuse by the autotrophs.
These events are repeated over and over again.
There is unidirectional movement of energy towards the higher trophic levels and its dissipation and loss as heat to the environment.- PSEB XII - 2025
