Is bacteria an abiotic or biotic factor?

Bacteria are considered biotic factors. Biotic factors refer to the living components of an ecosystem, which include all organisms such as plants, animals, fungi, and microorganisms like bacteria. These living factors interact with each other and can influence the structure and function of the ecosystem. Bacteria play crucial roles in various ecological processes, such as decomposing organic matter, recycling nutrients, and participating in nitrogen fixation. They can also form symbiotic relationships with plants and animals, which further illustrates their importance in ecological systems. In contrast, abiotic factors are the non-living components of an environment, such as sunlight, water, temperature, and minerals. Therefore, since bacteria are living organisms, they are classified as biotic factors.
