The title says all I'm asking. Thank you.

wikipedia said:The human body, consisting of about 100 trillion cells, carries about ten times as many microorganisms in the intestines. The metabolic activities performed by these bacteria resemble those of an organ, leading some to liken gut bacteria to a "forgotten" organ. It is estimated that these gut flora have around 100 times as many genes in aggregate as there are in the human genome.

http://www.sciencedaily.com/releases/1998/08/980825080732.htmWhen people think of bacteria, they likely first consider the nasty ones that cause disease, but the bacteria inside all animals combined -- including humans -- makes up less than one percent of the total amount. By far the greatest numbers are in the subsurface, soil and oceans.
The exact number of bacteria in the world is unknown, as they are present in every corner of the planet, including the soil, water, and air. However, it is estimated that there are around 5x10^30 bacteria on Earth, making them the most abundant organisms on the planet.
The number of bacteria found in the human body varies from person to person and depends on factors such as diet, hygiene, and overall health. However, it is estimated that the average human body contains around 30-40 trillion bacteria, which is roughly the same number as human cells.
Yes, bacteria are known to survive in a wide range of extreme environments, including hot springs, deep sea vents, and even in space. They have the ability to adapt and thrive in harsh conditions, making them one of the most resilient organisms on Earth.
The rate at which bacteria reproduce depends on various factors, such as the type of bacteria, environmental conditions, and available resources. Some bacteria can reproduce every 20 minutes, while others may take days or even weeks to reproduce.
It is difficult to determine an exact limit to how many bacteria the world can support, as it depends on various factors, including the availability of resources and competition with other organisms. However, it is believed that the Earth has the capacity to support a large number of bacteria due to their small size and adaptability.
