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.
All the living things, or organisms, and nonliving things that interact in a particular area make up an ecosystem. Organisms live in a speciï¬c place within an ecosystem. An organism obtains food, water, shelter, and other things it needs to live, grow, and reproduce from its surroundings.Some organisms make their own food in a process called photosynthesis. Other living things depend on plants and algae for food.The place where an organism lives and that provides the things the organism needs is called its habitat. An organism interacts with both living and nonliving parts of its habitat. The living parts of an ecosystem are called biotic factors.rganisms live in a speciï¬c place within an ecosystem.
