Fragmentation, leaching and catabolism are some of the important steps of decomposition. Study the following statements regarding these and select the correct option.
(i) Detritivores (eg earthworm) breakdown detritus into smaller particles.
(ii) Water soluble inorganic nutrients go down into soil horizon and get precipitated as unavailable salts.
(iii)Decomposers(eg. bacteria and fungi) secrete dogestive enzymes and degrade detritus into simpler inorganic substances.

As we have learnt in Functions of Ecosystem: Decomposition -
1. Fragmentation of Detritus:
- It takes place with the help of invertebrates like snails and earthworms.
- As they feed on detritus they are called detritivores.
- When detritus passes through their alimentary canal it gets fragmented or pulverised. This increases the surface area of detritus.
- They also add certain growth substances which help in the growth of microbes.
- A few detritivores are coprophagic, that is they can break down the faecal pellets of animals.
2. Leaching:
- This is the process by which simple and water soluble compounds percolate down to lower layers of soil with moving water.
3. Catabolism:
- During this process certain bacteria and fungi release extracellular enzymes.
- These enzymes help in converting decomposing detritus to inorganic forms.
- The enzymes are specific and work on a specific detritus, for example Pseudomonas bacteria decomposes proteins into ammonia and simple nitrogen compounds.
Hence, the correct option is (c).
