EXTRACELLULAR DIGESTION
Bacteria ( and fungi) consume food by excreting enzymes that digest the food material outside of the bacteria. The result is small(ish) molecule ( compared to the original fod material) that can be absorbed into the bacteria thru the cell wall and membrane ( no mouth!)
Heterotrophic bactera are saprobes (they absorb dead organic material like rotting flesh). Some of these parasitic bacteria kill their host while others help their host.
Autotrophic bacteria make their own food, either by photosynthesis (which uses sunlight, carbon dioxide and water to make food) or by chemosynthesis (which uses carbon dioxide, water and chemicals like ammonia to make food - these bacteria are called nitrogen fixers and include the bacteria found living in legume roots and in ocean vents).

What is bacteria that has the ability to create their own food?
Autotrophs, just like flowers and grass, bacteria make their own food too! Bacteria are sometimes also heterotrophs as well. That means the oposite of aoutotrophs, they don't make their own food. Hope i helped :)
How bacteria get their food?
Bacteria get their food by absorbing it. Many bacteria will photosynthesize just like plants do in order to get food.

Harmful bacteria in food can be killed by?
Cooking the food. Raising the heat to te proper level kills bacteria.
Do hot spices prevent the absorption of bacteria from food?
No, hot spices will not prevent absorption of bacteria from food, nor will it prevent bacteria from growing on the food.
Bacteria can only take in food if the food is?
If the food can be degraded into small molecules, so it can then be absorbed by the bacteria.
