Most of 'em none, cause most don't live in our body. The ones that obligatory need humans, would need to find other hosts. Then they'd have to adapt to other animals, especially to get in and out of these hosts. Then they'd need to find a way to adapt to the tissue they inhabit, concerning pH, temperature, gas pressure, nutrients. Furthermore they need strategies to inhibit the animals immune system.
Organisation. Bacteria have cellular level of organisation and humans have organ system level of organisation.
Without bacteria, nutrient cycling would be disrupted, leading to dead organic matter accumulating and nutrient availability decreasing. Additionally, our immune systems rely on beneficial bacteria for development and function, making us more susceptible to infections and diseases. Lastly, certain industries such as food production and waste management rely on bacterial processes for efficiency and sustainability, which would be severely impacted.
Humans carry a wide variety of bacterial species on their skin, in their mouth, gut, and other body sites. Some common bacteria found on or in humans include Staphylococcus aureus, Escherichia coli, and Bacteroides fragilis. These bacteria can have both beneficial and harmful effects on human health.
Bacteria are single-celled microorganisms that lack a nucleus and organelles. They have a cell wall and reproduce through binary fission. Bacteria can be beneficial or harmful to humans and other organisms.
In space, without oxygen or bacteria, decomposition would not occur. A dead body in a suit would be well preserved due to the extreme cold temperatures and lack of oxygen, essentially mummifying it. Without a suit, the body would be exposed to radiation and extreme temperatures, causing it to freeze-dry and mummify as well.
None.
They are not, bacteria is the most important species - without them humans would not last more than a few hours.
The sun. Without the sun humans would be extinct and so would all other living matter except for maybe bacteria.

well, without humans, the world will have no problems ,like global warming, pollution. But there won't be any pluses like, cures, and many animals would be injered and would get infected, but i guess that's natural. Before we were here that's what happend. Good question. I hope i helped you get an idea. 2nd answer Don't know. How would we know if there is no humans.
animals would have our jobs
If we were to completely eliminate all bacteria from the world, ecosystems would collapse as they play crucial roles in nutrient cycling and decomposition. Additionally, humans and other animals rely on certain bacteria for digestion and immune system function. Overall, the absence of bacteria would have severe and widespread negative consequences on life on Earth.
Humans getting milk from cows would be an example of commensalism. Commensalism describes a relationship that exists between two organisms in which one organism benefits without harming the other organism.
we would not have tv,xbox and alot of other things
