This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web.
a) bacteria and fungi, the decomposers, recycle carbon from dead organisms.
b) carbon is found in the grass and is passed from one level to the next in this food web.
c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere.
d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

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.
