Explanation:
C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.
Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.

The most common bacteria causing SBP are gram-negative Escherichia coli and Klebsiella pneumoniae and gram-positive Streptococcus pneumoniae usually only a single organism is involved. Spontaneous bacterial peritonitis (SBP), an infection of ascitic fluid without a definitive intra-abdominal source that can be surgically treated is a common complication in patients with cirrhosis and ascites. Spontaneous bacterial peritonitis (SBP),is treated with a 10 to 14 day course of antibiotics .
