What type of symbiotic relationship exists between a cow and the bacteria that live in your mouth?

The relationship between a cow and the bacteria in its mouth can be considered a mutualistic symbiOSis. The bacteria help break down complex carbohydrates in the cow's diet, aiding digestion, while the cow provides a habitat and nutrients for the bacteria to thrive. This mutual benefit enhances the cow's ability to extract energy from its food and supports the bacterial population.
