Mature and established trees die for a combination of reasons but sudden browning of foliage is typically associated with a lack of water supply to the canopy. Water supply can be cut off to the canopy due to obvious issues including deficiency or root damage.

<h3>What is Carbon?</h3>
  • Carbon is a chemical component with the symbol C and atomic number It is nonmetallic and tetravalent—its atom makes four electrons unrestricted to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon produces up only about 0.025 percent of Earth's crust.
  • Carbon is employed in some way in almost every industry around the globe. It is used for fuel in the form of coal, methane gas, and crude oil (which is used to produce gasoline). It is used to make all sorts of fabrics including plastics and alloys such as steel (a mixture of carbon and iron).
  • Carbon is a chemical element with the symbol C and atomic number 6. Categorized as a nonmetal, Carbon is a solid at room temperature.

Carbon dioxide is very essential for the process of photosynthesis. Thus, during day time when stomata is open photosynthesis takes place while during night time when stomata is closed photosynthesis do not occur. Also the stomata regulate the loss of water from the leaves thereby ensuring availability of sufficient water molecules at the time of photosynthesis.
