260253 Which one of the following processes during decomposition is correctly described?

1 Leaching - Water soluble inorganic nutnents rise of the top layers of soil
2 Fragmentation - Carried out by organisms such as earthworm
3 Humification - Leads to the accumulation of dark coloured substance humus which undergoes microbial action at a very fast rate
4 Catabolism - Last step in the decomposition under fully anaerobic condition

260255 The bacteria which attack dead animals are

1 first link of the food chain and are known as primary producers
2 second link of the food chain and are herbivorous
3 third link of the food chain and are tertiary consumers
4 the end of food chain and are decomposers.
