<span>The absence of the predator in the experimental plots led to a rise in population of the two species hence suppressing the other species since they were the prey of the Sea stars. But when the sea stars were present, they maintained a balance in the species diversity by feeding on Mussel and Barnacle species.</span>

Answer:
Both Cohesion and adhesion play an important role in the upward movement of water through a plant.
Explanation:
Water is absorbed by the roots and transported by xylem tissue to various parts of a plant body such as stem ,leaf .
During the transportation of water molecules through the xylem tissue formation of hydrogen bond occur between the water molecules. A single hydrogen bond is weak but collectively they exert a very strong interaction.As a result a water column is established in the xylem tissue. This is called cohesion.
Adhesion deals with the interaction of water column with the wall of the xylem tissue.
