Fire ant is the common name for several species of ants in the genus Solenopsis. They are however only a minority in the genus, which includes over 200 species of Solenopsis worldwide.Solenopsis are stinging ants and most of their common names reflect this, for example, ginger ants and tropical fire ants.Many species also are called red ants because of their light brown colour, though species of ants in many other genera are similarly named for similar reasons.ire ants often attack small animals and can kill them. Unlike many other ants, which bite and then spray acid on the wound, fire ants bite only to get a grip and then sting (from the abdomen) and inject a toxic alkaloid venom called Solenopsin, a compound from the class of piperidines.
Alkalinity is important for fish and aquatic life because it protects or buffers against rapid pH changes. Living organisms, especially aquatic life, function best in a pH range of 6.0 to 9.0. Alkalinity is a measure of how much acid can be added to a liquid without causing a large change in pH. Higher alkalinity levels in surface waters will buffer acid rain and other acid wastes and prevent pH changes that are harmful to aquatic life.
Upper and Lower Values, and Temperature Range Some species of microorganism can grow at temperatures as low as -10 o C, and others at temperatures as high as 100 o C-or higher. These upper and lower values are a function of cell metabolism.pper and Lower Values, and Temperature Range Some species of microorganism can grow at temperatures as low as -10 o C, and others at temperatures as high as 100 o C-or higher.
