Question

how bacteria obtain their food​

Answer 1

Answer:

1. The first way bacteria can obtain food is via photosynthesis. Like plants, many bacteria contain chloroplasts or blue-green pigments, which means they can photosynthesize and thus create their own food by absorbing sunlight. Because these bacteria can create their own energy, they are classified as autotrophs.

2. The second way bacteria can obtain food is through chemosynthesis, of which there are two types: Autotrophic chemosynthesis, and heterotrophic chemosynthesis.

3. The third way bacteria can obtain food is through symbiosis , of which there are three types: Mutualism, Commensalism and Parasitism.
