What would the relationship be between grass and a hawk?

They both can be found in the same food chain, but they aren't directly related. A hawk is a tertiary consumer (top of the food chain) and grass is a producer (bottom of the food chain). The hawks survival depends on grass:

Grass feeds on nutrients from the ground → insects eat grass and flowes → bigger insects eat the smaller insects → field rats eat the insects → hawks eat the field rats.

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.
