Answer 1

b. decaying dead matter

Answer 2

One of the characteristics of humus is- b) decaying dead matter.

• Humus is a dark coloured, non-living matter that is formed due to the slow and partial decomposition of dead remains of plants and animals.
• The decomposition takes place by the action of some soil microorganisms known as decomposers.
• This layer of soil makes the soil fertile as it is rich in nutrients and organic matter.
