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.
Human blood has a pH of between 7.3 to 7.5, which is slightly on the basic side of the scale. If blood pH drops below 7.0 or goes higher than 7.8 the body can no longer function and dies. There are many other everyday implications to pH values. 1  Acidic soils must often be treated with lime, which is an alkaline substance,to neutralize the pH before planting. The pH will determine what type of plant will grow and thrive in the soil. In a marine environment, including an indoor aquarium, a basic pH of 8.1 to 8.4 makes it easier for fish to maintain their own cleanliness and resist illness. It has a slight antiseptic effect. pH describes the balance between hydrogen ions and hydroxide ions.
