Question

Q6. DEFINE THE NITROGEN CYCLE.

Q7. DISCUSS WITH EXAMPLE ANY THREE MEDICINAL USES OF MICROORGANISMS.

Q8. HOW DOES MALARIA SPREAD FROM ONE PERSON TO ANOTHER.

Q9. WHAT ARE COMMUNICABLE DISEASES GIVE THREE EXAMPLE.

Q10. NAME ANY TWO DISEASES CAUSED BY MICROORGANISMS IN ANIMAL AND PLANTS.​

Answer 1

Ans1. The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. 

Ans2. (i)Production of dairy products: Bacteria are the key players here.

(ii) Bread Baking: A species of Streptococcus is added to the dough before making bread to bring about the required fermentation.

(iii) Butter is made by churning the cream which has been soured by lactic acid bacteria.

Ans3. Malaria spreads when a mosquito becomes infected with the disease after biting an infected person, and the infected mosquito then bites a noninfected person. The malaria parasites enter that person's bloodstream and travel to the liver.

Ans4. Communicable, or infectious diseases, are caused by microorganisms such as bacteria, viruses, parasites and fungi that can be spread, directly or indirectly, from one person to another. Some are transmitted through bites from insects while others are caused by ingesting contaminated food or water.

Some examples of the reportable communicable diseases include Hepatitis A, B & C, influenza, measles, and salmonella and other food borne illnesses.

Ans5. Diseases in animals caused by bacteria are anthrax, blackquarter and tuberculosis. Bacteria can infect wounds, and that is why wounds should be treated.

Bacterial diseases can be grouped into four broad categories based on the extent of damage to plant tissue and the symptoms that they cause, which may include vascular wilt, necrosis, soft rot, and tumours. Vascular wilt results from the bacterial invasion of the plant’s vascular system.

✿ Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.
