Bacteria are primarily classified as decomposers in the ecosystem, as they break down organic matter and recycle nutrients. Some bacteria are also considered autotrophs, such as photosynthetic or chemosynthetic bacteria, which produce their own food. Additionally, certain bacteria can act as pathogens, consuming host tissues. Overall, bacteria play versatile roles in various ecological niches, contributing to nutrient cycling and energy flow.
