Final answer:
Microbes have contributed to our health and well-being by aiding in digestion, producing essential nutrients, protecting us from pathogens, and regulating our moods and weight. The gut microbiome is particularly important for our overall health.
Step-by-step explanation:
Microbes have made significant contributions to our health and well-being. They help us digest our food, produce essential nutrients, protect us from harmful pathogens, and contribute to the proper functioning of our immune system.
For example, the commensal bacteria in our gut not only aid in digestion but also regulate our moods, influence our activity levels, and even help control weight. The gut microbiome, which consists of trillions of bacteria, is considered a multicellular organ that plays a crucial role in our overall health.
