Secondary succession

Explanation:

Weeds growing in a recently burned patch of forest can be considered as secondary succession. This is because earlier there used to be a forest which has been recently burned.

In case of secondary succession, the species grow in an environment which once has biological species and due to some natural or man made disaster it is finished.

After sometime the species starts growing on the same place where they were present earlier is known as secondary succession.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
