Is helminthis a bacteria?
No, it is a parasitic worm
"Bacteria producing bacteria" - this is not a specific type of bacteria, as you might say a dog is a specific type of animal. All bacteria reproduce, and form new bacteria through a process usually called binary fission. In this way, each bacteria produces more new bacteria. It is not a trait of one species of bacteria.
There are many kinds of bacteria. Some bacteria is good for your body, and if you get rid of too much bacteria you can get a infection. [For example when you don't have enough bacteria in your vagina that's when you get a infection down there]. But you also can have problems if you have too much bacteria or a bad bacteria, it all depends on the type of bacteria.
Bacteria do eat other bacteria, using mechanisms such as phagocytosis and endocytosis. Bdellovibrio bacteriovorus is a kind of bacteria which feeds on other bacteria. It is the purifying agent of water in the River Ganges. Research is being done to see if such bacteria can be used to kill bacteria that cause diseases.
Photosynthetic bacteria The bacteria that use photosynthesis are called photosynthetic bacteria. Examples of photosythetic bacteria include cyanobacteria, green sulphur bacteria and purple sulphur bacteria. They posses chlorophyll or other photosynthetic pigments which is not isolated in chloroplasts. The purple bacteria and green sulphur bacteria utilize H2S instead of H2O and liberate sulphur instead of oxygen.
some good things about bacteria is that bacteria may get you sick but bacteria is also what some people use in medicines that can cure what you might have from bacteria for example bacteria is used in germ-x and hand sanitizers so when you get bacteria and you go to take care of it your just getting good bacteria to kill the bad bacteria it's like a war.
