Most bacteria consume things already dead. They decompose stuff like shed skin, carcasses, and plant bits such as leaves. These do it by secreting digesting enzymes outside themselves onto the food source. The bacteria then absorb just what they need.

Other bacteria can photosynthesize. These include the cyanobacteria that produce oxygen for our atmosphere. They still contribute up 30% of the Earth available oxygen every year. Then there are the purple nonsulfur bacteria that do both, photosynthesize and get their energy from organic compounds.
Some symbiotic bacteria help us digest the food we consume. These beneficial gut flora provide us with essential nutrients like vitamin B1 & B6 we cannot make ourselves. There are over 800 known species living in humans but people do not have all. Different populations of people have different collectives of gut bacteria. Understanding what a specific group of bacteria do in the gut and how they work together to digest may affect how we get energy from our food and gain weight.
Bacteria gets its nutrients mainly from dead things. The main function of bacteria is to decompose living things once they die and by doing this it gets it nutrients.
Some do, yes. Its not exactly "eating" but a process known as "phagocytosis."
Bacteria is the most important organism because bacteria gets the nutrients from dead plants and animals, and then it provides the nutrients for the grass to be able to grow.
The earthworm gets nutrients the same way most other animals get nutrients, by eating and digesting them. The earthworm digests dirt and bacteria and enzymes in the dirt in order to utilize the vitamins and minerals it needs to survive.
Bacteria that "eats" oil for nutrients.
Bacteria collects nutrients from dead organisms.
Bacteria that invade a host organism and obtain nutrients from the host's cell are pathegonic bacteria.
It gets old and then bacteria gets in.
pathogenic bacteria.
it gets it nutrients from the yolk of the egg it gets it nutrients from the yolk of the egg
