How many harmful bacteria live on Earth?

Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.

Many different kinds of bacteria live in the intestines. They assist in digestion of foods and keep harmful bacteria from in check.

of course there are many harmless and useful bacteria that our live depend on

There are harmful to all organisms, but some bacteria are helpful in many ways.

A person has "good" bacteria in the large intestine. These are often called probiotics. A person also has many on the skin and they crowd out harmful ones.

There are a great many ways that bacteria can be harmful. Bacteria can definitely cause decomposition and sickness for example.

Blue green bacteria has color pigments and bacteria doesn't and bacteria is made with many products for humans to use and blue green is harmful they live inc ponds ,mrivers , lakes

it contains the temperature of the Earth and blocks harmful rays from the sun and from outer space. with out it, Earth would be either too hot or too cold to live in and many harmful rays would reach and destroy the earth

There are many, many types of bacteria. They can be both harmful and helpful to us. Also, even if there were to be helpful in a certain part of the body they may also be a pathogen in another.

some harmful effects of bacteria include: can cause decease's, sickness, unusual behavior in victim, spoil food. But there are many more.

Bacteria would consider benefitial and harmful bcz many food component are you eating made by bacterial reactions like yeast... but most of spp. are harmful.

some harmful effects of bacteria include: can cause decease's, sickness, unusual behavior in victim, spoil food. But there are many more.

Not every bacteria is harmful to us. Some like the gut bacteria are very essential for their survival. But many bacterias like the Salmonella Typhi causes typhoid and so on..... -Ashish Mradul

Yes. Your skin has many types of bacteria that are needed to fight off more harmful bacteria. Females have bacteria that help fight off fungal infections. When a bacteria population reaches a certain number it is no longer helpful, and thus considered pathologic

There are many bacteria that serve beneficial roles. Bacteria in the environment break down dead matter and waste, allowing it to be re-used by other living things. Some soil bacteria convert nitrogen into a form that plants can use, allowing them to grow. Many animals, including humans, have bacteria in their digestive tracts that aid in digestion and protect against harmful bacteria. We could not live without bacteria.

Normally this would come under biology, However many bacteria are involved in geological processes (e.g. stromatolites) and it has been found that bacteria live deep down in the rocks of the planet. Thus were bacteria are involved in this way their study would be of concern to the earth scientists too.

Prokaryotic Cells are the smallest cells present such as bacteria. Many harmful bacteria can cause infenction.

Many animals are carnivorous in nature. Many animals carry harmful bacteria to humans.

more than 1/4 than you already have

bacillus means rod shape bacteria and many of them are harmfull like Bacillus anthracis, Haemophillus influenzae etc.

it has very many harmful effects on your life because if it get in your system it will spread and u will die if u dint get help

Well some bacteria can be beneficial to humans in some ways like yogort, bread and many other things they are made from or have a good kind of bacteria in them

Well, you can think of bacteria. Many cause diseases. For example, 2 bacteria that damage the stomach is Heliobacter Pylori and E.Coli.

Tidal energy is natural and is not harmful to the Earth. Scientists are currently studying ways to make use of tidal energy because of its many benefits.

Anaerobic organisms do not require oxygen to survive. On earth, those organisms are limited to many types of bacteria and obligate anaerobes.

Like bacteria, many fungi are decomposers. For example, many fungi live in the soil and returns important nutrients to the soil. Without fungi and bacteria, Earth would be buried under dead plants and animals

Counting all the bacteria on earth is is impossible. Even estimating is nearly impossible. my guess is: 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 and probably more then that!!

In a word, no. The human body (along with many, many animals on earth) use basteria in their system to their advantage. They are produced by the body to eliminate foreign bodies (read:disease) and to digest food, among other things.

Yes. There are billions of different bacteria living inside your mouth. About 100,000 per tooth and millions on your tongue. The only way to get rid of harmful bacteria is wash your mouth daily and brush your teeth 3 times a day. Many of the bacteria is harmful that lives in your mouth so be careful what you put inside it because then it could multiply!

There are many types of bacteria some of which don't need to live inside another organism.

Because many forms of life are dependent upon a symbiosis with certain species of bacteria. And many bacteria are necessary as decomposers.

Commensal organisms like bacteria on the skin make it more difficult for harmful bacteria to grow. However, the commensal organisms can be harmful to people with depressed immune systems. They could also cause inflammation if there are too many of them.

Two roles of helpful bacteria are ♥ to keep the numbers of harmful bacteria in check. They do this by occupying the skin space, leaving little or no room for harmful bacteria to reproduce and grow and ♥ to produce acids that lower the skin pH. Many disease causing microflora do not survive well in a low pH environment.

Bacteria can be categorized as living cells unlike viruses. Bacteria are found everywhere from the tallest mountains to the deepest parts of an ocean on earth. The air is replete with bacteria. Certain bacteria spend their whole lives in the atmosphere, reproducing and growing in the clouds. Although bacteria lack distinct nuclear structures common to the cells of higher organisms like animals and plants and are able to reproduce successfully and transfer genetic information from…

There are many differences * Bacteria are microscopic while human is not. * Bacteria are prokaryotes. Human is eukaryote. * Bacteria has a cell wall. * Bacteria are the earliest known organisms on earth.

Not all bacteria harm us, many of them are very friendly and useful because they help us digest our food. Others, that are harmful, destroy our body tissues.

Almost every disease is caused by a microbe. Bacteria, viruses, amoeba, yeast plus many more.

The acidity of the stomach prevents the growth of many micro-organisms (such as bacteria), which could be harmful to your health.

yes! there are many very harmful types of bacteria in feces which can make you very ill!

Bacteria are one-celled organisms. Here are some sentences. Bacteria cause many infections. Many bacteria can live in places no other organisms can. Scientists have found traces of bacteria on asteroids.

It depends on what kind of bacteria you're talking about. Many bacteria in our own bodies are useful and helpful - for example, the bacteria in our digestive system that takes food and converts it in to the elements we need to survive. Other bacteria can be deadly, such a staph bacteria that cause infections. Bottom line is that not all bactiera are harmful.

Most bacteria are either harmless or beneficial to humans, but there are some that can cause harm. Many bacteria are able to cause disease and even death. For example, Clostridium botulinum can cause food poisoning that is sometimes fatal.

Ochrobactrum Anthropi is simply a bacteria that helps clean up many enviromental spills. For example, this bacteria is commonly used by scientists to clean up oil spills. The bacteria helps eat it, and then converts it into harmful substances.

Both bacteria and the lining cells of the intestinal tract have to have mutual attractive proteins. These will allow the bacteria affect the other cells. Many do not and they have no bad effect. We do have billions of bacteria that are beneficial and not harmful. The digestive tract is their normal habitat.

hey can destroy the nervous system and slow down the process of digestion.

Not at all. They are harmless and do not carry diseases nor do they give bacteria that cause warts, as many people believe.

There are many people who care about our planet. Earth is where we live, and will continue. If we don't care about Earth, how are we going to live?

Bacteria are small, single-cell organisms that are both beneficial and harmful to human beings. Some forms of bacteria help us to live, such as those that help to break down food in our intestines. Other forms, such as the bacteria that causes the Bubonic Plague, can kill a person if left untreated. There are many different types of bacteria and they respire using different methods. The two primary methods of bacterial respiration are aerobic respiration…

Yes, ginger has many health benefits. It is said that it helps kill some bacteria, ex. it is often eaten with sushi either in condiment form or whole in order to prevent illness from harmful bacteria from the raw fish.

none :) a bacteria is considered to be unicellular but there are many bacteria that live in clusters or are filamentous, in that case the intercellular interaction is more important and we can in a way see that as a multicellular organism. Theoretically a bacteria is unicellular , always !!
