You would not be able to digest your food properly.
Yes they do. In fact, without bacteria in our guts to digest food, we would soon die.
Not exactly but food, like any gas, liquid or solid, is made up of one or more chemicals. Plants growing is 'chemical change'. Food rotting is 'chemical change' Cooking food is 'chemical change'. Without 'chemical change' or chemical reactions, plants would not exist. Human beings would not exist. Anything we eat would not exist. Planet Earth would not exist!
Without producers, consumers would not exist.
As some bacteria are harmful, there are some good things about bacteria in general. 1. If it weren't for bacteria, we wouldn't be here. All organisms on earth can trace their roots back to one group of organisms -primitive precambrian bacteria. If it weren't for those, complex life (like us) wouldn't be able to exist. 2. Bacteria aid in the digestive process. 3. Cheese, yogurt, and many other foods would not exist. 4. If it weren't for bacteria, the corpses would just pile up. Most bacteria are decomposers, meaning that they utilize dead or decaying matter for their food source. Without them, dead bodies would just sit there and not go away. There wouldn't be enough soil in the world to bury them all -in fact, without bacteria, there would be no soil -which takes us to our fifth positive aspect of bacteria. 5. Most people say that plants are the bottom of the food chain. The base of all life. They're wrong. In a terrestrial ecosystem, a plant would need soil for nutrients. Without bacteria, soil could not exist. In an aquatic ecosystem, such as an ocean, big fish need to eat little fish who prey on krill who eat plankton. Most people think it stops there. While some plankton are autotrophs (phytoplankton), the heterotrophic ones (zooplankton) find their metabolic sustenance from dead matter or -you guessed it- bacteria.

Breeding isn't useful, it is a must, without breeding there would be no food and every living organism would cease to exist.
Fungi are just as essential to our biology as other microorganisms. Without them we would be lacking food and medicine.
Dehydrating food removes moisture, which is essential for bacteria to grow. Without moisture, bacteria cannot thrive and spoil the food, allowing dehydrated food to have a longer shelf life. Additionally, packaging dehydrated food in airtight containers further prevents bacterial contamination.
You wouldn't live. You wouldn't even get "sick". Without any immune system at all, your body would just rot as the bacteria and fungi ate it.
No, food would not exist without the sun, as it is essential for the process of photosynthesis, which allows plants to convert sunlight into energy. These plants form the foundation of the food chain, providing energy for herbivores and, in turn, for carnivores. Additionally, the sun's heat helps regulate climate and weather patterns, which are crucial for agriculture and food production. Thus, without the sun, the ecosystem that produces food would collapse.
Life depends upon there being a supply of oxygen, water and food. Without these, life would cease to exist.
