After some time roots develop from the covered part. This is called a layer. Now the branch can be cut from the parent and a new plant is produced.

Answer 2

Answer:

Yes, it is true. Microorganisms are responsible for the breakdown of dead plant and animal matter. They convert the dead plants and animals into matter that can be absorbed by the plants, as per the nitrogen cycle. With no microorganisms, the plants and animals would not decay, and plants wouldn't get enough nutrients to survive, and they would eventually die.
