Select the incorrect statement w.r.t decomposition. (a) Bacterial and fungal enzyme degrade detritus into simpler inorganic substances in a process is called catabolism. (b) Humans is less resistant to microbial action and undergones decomposition at an extremely slow rate. (c) By the process of leaching , watersoluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts. (d) Decomposition is largely an oxygen requiring process.

The dark coloured amorphous substance formed during the process of humification is

Which of the following processes of decomposition produces a substance resistant to microbial action?

Which of the following processes of decomposition produces a substance resistant to microbial action?

True or False. Those substances which have extremely high resistance are called insulators.

Name the dark coloured substance formed by the action of decomposers on dead plant leaves.
