Harmful bacteria Pathogenic Bacteria These bacteria cause great losses to plant and animal population by causing several diseases. Reduction of Soil Fertility Some facultative anaerobic bacteria are available mostly in the oxygen deficient soil which reverse the nitrifying process, thereby causing the loss of a part of its combined nitrogen. They break down the … Read more Uses And Harms Of Bacreria

Vector borne diseases Main vectors and diseases they transmit Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Many of these vectors are bloodsucking insects, which ingest disease-producing microorganisms during a blood meal from an infected host (human or animal) and later inject it into a new … Read more Vector Borne Diseases
Pros of Nuclear Energy Low Pollution: Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn’t discharge any gasses … Read more Uses And Harms Of Nuclear Energy
