Final answer:
We have a mutualistic relationship with the microbiome, an ecosystem of microorganisms including bacteria, which helps us in many ways such as digestion and nutrient production. The human microbiome is a diverse community that influences various aspects of health, and hygiene and diet can impact its composition.
Step-by-step explanation:
We have a mutualistic relationship with our microbiome, the collection of microorganisms that reside in and on our bodies. The relationship between humans and these microorganisms is characterized as mutualism, a type of symbiotic relationship where both parties benefit.
The commensal bacteria that inhabit our skin and gastrointestinal tract are crucial for health, influencing everything from mood regulation to obesity. These microbes, including the well-known gut microbiome, often outnumber human cells by up to an order of magnitude. The human microbiome includes both resident and transient microbiota which can be influenced by factors such as hygiene and diet.
