Cross feeding is categorized as which type of interaction?

• A. Cooperative
• B. Neutral
• C. Antagonistic
• D. Competitive

Answer: (A)

Cross feeding shows cooperative metabolic interdependence in a microbial community. One microbe releases a metabolite that another uses, supporting the growth and survival of the recipient and often creating a linked relationship where the partners rely on each other. This differs from neutral interactions (no effect) or antagonistic/competitive ones (where organisms harm or directly outcompete each other for the same resources). A common oral example is a producer microbe releasing a compound that a partner species can consume, contributing to a more stable biofilm community.
