Carbonic acid

Explanation: The carbon dioxide when get dissolved in the water is known as carbonic acid. This carbon dioxide from the water is used by the pytoplanktons to perform the process of photosynthesis.

This is a very weak acid which is formed when the carbon dioxide gets dissolved in the water. The carbon dioxide in the environment goes inside the  ocean that is used by the organisms and oxygen is released into the environment and inside water.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

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.
