Which of the following is called detrivore?
1 An animal feeding on a plant
2 An animal feeding on another animal
3 An animal feeding on decaying organic matter
4 Plant feeding on an animal
Explanation:
Detritivores (e.g., earthworm) break down detritus into smaller particles. This process is called fragmentation.

Which one of the following processes during decomposition is correctly described?
1 Catabolism - Last step in the decomposition under fully anaerobic condition
2 Leaching- Water soluble inorganic nutrients rise to the top layers of soil.
3 Fragmentation - Carried out by organism such as earth worm.
4 Humification -Leads to the accumulation of a dark coloured substance humus which undergoes microbial action at a very fast rate.
Explanation:
Breakdown of complex organic matter into inorganic substances is called decomposition.Dead plants remains, dead animals are called detritus, which is the raw material for decomposition. Fragmentation is the breakdown of detritus into small particles with the help of detritivores. Leaching is the process in which water soluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts. Degradation of detritus into simpler inorganic substances with the help of bacterial and fungal enzymes is called Catabolism

The organic substances, which decompose slowly are
1 Chitin and Lignin
2 Rich in nitrogen
3 Rich in water-soluble substances like sugars
4 All of these
Explanation:
Decomposition rate is slower if detritus is rich in lignin and chitin
