How does bacteria get there food?

Answer 1

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).

Answer 2

Bacteria obtain their food by breaking down organic matter such as sugars, proteins, and fats through a process called enzymatic digestion. Some bacteria are able to produce their own food through processes like photosynthesis, while others rely on consuming dead organic material or other organisms for nutrients.

Answer 3

Bacteria is everywhere on the planet. There's more bacteria than any other life form. In fact, in the human body there are more bacteria cells than human cells.
