DESTRUCTIVE
1. Eutrophication
The main effect that would happen is algal blooms where the stream, lake or ocean is covered with algae. This blocks sunlight from reaching the water this it prevents aquatic plant from photosynthesizing.

2. Acquired Immunodeficiency Syndrome (🤬)
It is caused by a virus named HIV (Human immunodeficiency Virus). It takes over cells vital to the immune respond which is known as CD4 + lymphocytes. This causes the cell to interfere with body’s ability to fight off infections, cancers and other disease.

3. Food Spoilage
This occurs as the food is exposed to air and surroundings. It is the change of look, consistency, flavor and odor of the food which is caused by bacteria, moulds and yeast. For example, lactobacillus causes the formation of lactic acid while proteus causes the formation of gas.

BENEFITS

1. Genetic Engineering
Genetic Engineering is an artificial recombination of DNA from two organisms. Bacteria can be genetic engineering to produce useful human proteins such as insulin. This could happen by inserting human insulin gene into a bacteria plasmid to gain the ability to produce insulin.

2. Decomposition
This is a natural process that causes large organic materials to be broken down into simpler ones which usually involves bacteria and fungus. Without the help of microorganism to undergo decomposition, the whole world would likely to end up with overcoming piles of dead biomass. Other than that, decomposition helps to recycles back nutrients to the soil.

3.Bioremediation

Bioremediation is the biodegradation of pollutants by microorganisms. It involves solving and removing dangers of many pollutants through biodegradation from environment. Microorganisms really help to restore original natural surroundings and prevent further pollution

# data[].attributes.body
A destructive action of microbes is that they caused diseases.These Disease-causing microbes are not just affecting human but also plants and animals.

In human they attack our immune system .Because they are very quick at adjusting to new environment making it becomes so hard to get rid of them,in other words,they quickly become resistant to the 🤬 that were once killed them.They can also contribute to chronic diseases such as:
-Acquired Immunodeficiency Syndrome(🤬)
-Some form of cancer

A beneficial action of microbes is that whether we believe it or not they do protect our body.

Example:
- Bacillus subtilis. It can be found on the skin, and it makes bacitracin, a poison that helps it fight off other microbes.
- H. pylori helps protect against asthma, allergies and even cancer.

Yeast( saccharomyces cerevisiae) is used for the purpose of baking bread. Since, it is also known as ‘baker’s yeast’.

2 . They are used in the production of alcohol from Sugar or starch and wine from fruit juice by the process called fermentation.

3. In the cleaning of the environment by breaking down the organic waste into harmless and usable substances.

Anaerobic bacteria degrade the animal dung into biogas

DESTRUCTIVE ACTIVITIES OF MICROORGANISMS :

1. It causes many types of diseases in humans.

Clostridium tetani is a pathogenic bacterium that causes tetanus.

🤬 that is caused by HIV virus.

Maleria is caused by parasite plasmodium.

Tuberculosis is caused by a bacterium-called Mycobacterium tuberculosis.

2. It also cause diseases in animals such as;

Anthrax disease that is caused by bacterium can affect cattle,humans.

The disease cholera that is caused by bacterium can affect the poultry birds.

The disease Dermatitis caused by virus can affect the goat,sheep.

The disease Rinderpest caused by bacterium can affect cattle.

3. The microorganisms spoils the food

The bacterium staphylococci causes food poisoning by producing a heat-resistant toxin in the food.

The bacterium Clostridium botulinum causes a rare, but dangerous form of food poisoning known as Botulism. Thus,microorganisms, spoil the food.

Beneficial activities of microorganisms:
1) Some microorganisms are used to produce food products by a process known as fermentation.
2) microorganisms allow us to artificially grow helpful substances such as insulin and human growth hormones
Destructive activities of microorganisms:
1) microbes cause infectious diseases:
- Bacteria: Causes various diseases such as typhoid, diarrhea, and cholera.
-Algae: Algal boom in water (rapid growth of algae) causes poisonous effect after they die, which in turn results in the death of aquatic organisms.

Beneficial activities of microorganism in agriculture
1)soil microbes (bacteria and fungi) are essential for decomposing organic matter
2)Some soil and bacteria provide important nutrient like nitrogen and phosporus
3)The plants infected by virus more tolerant of drought
Destructive activities of microorganism
1)Agriculture have  to face destructive activities of numerous pest like fungi and weeds which had serious effect on production
2)Global crop yield reduce due to plant pest and diseases
that cause by destructive microorganism

Beneficial activities of microorganisms:
1)Fungi can colonize upper parts of plants and provide many benefits, including drought tolerance, heat tolerance, resistance to insects and resistance to plant diseases.
2)Some soil bacteria and fungi form relationships with plant roots that provide important nutrients like nitrogen or phosphorus.
Destructive activities of microorganisms:
1)Plant disease...bacteria, viruses, cell-worms and fungi cause the most severe losses. They destroy field crops, forage crops, fruit and nut crops, vegetable crops, drug plant crops and ornamental crops.
2)Destruction of timber product...Several fungi like Polyporus, Chloros-plenium, Penicilium divaricatum, Fusarium negundi. Pori microspora, Lentinus lepidens are responsible for decay of standing trees, decay of felled timber, sap stains and decay of wood in various uses.

DESTRUCTIVE ACTIONS OF MICROORGANISMS:
1) it causes food spoilage
2) responsible for half of all human diseases(PATHOGENIC)-influenza, communicable diseases, tuberculosis, malaria(agent is plasmodium sp.), athelete"s foot.
BENIFICIAL ACTIONS OF MICROORGANISMS:
1)recycling of chemical elements in ecosystem- increase availability of nutrients that is required for plant growth.
2)bioremediation- use of organisms to remove pollutants from soil, air, and water
3) food production such as yogurt, cheese, alcoholic beverages(fermentation)
4) bacteria are used in sewage treatment.

Benefits :
- It helps in fermentation (for example yeast, that is responsible for the production of bread and yoghurt).
- It can be made into vaccines and antibiotics.
- It can helped human and animals bodily function and also prevent them from infection.
- It can absorbs toxins.

Destructive Actions :
- Even though yeast made up the food, it can also spoil the food and decomposing it.
- Microbes can caused diseases such as TB, cholera and typhus.
- It can be used as bioweapons which can harm our respiratory system.
- It also can trigger allergic reactions (for example spores allergic, etc)

In conclusion, microbes have both positive and negative impacts, so, it is still both necessary for our lives.
