microbial life

Microbial life consists of tiny organisms called microbes, including bacteria, viruses, fungi, and protozoa. These microorganisms are incredibly diverse and found everywhere—from the deepest oceans to our own bodies. They play essential roles in ecosystems, such as recycling nutrients, helping plants grow, and supporting our immune systems. Some microbes cause diseases, but most are harmless or beneficial. They are fundamental to life on Earth, acting as both the planet’s smallest inhabitants and powerful agents of biological processes that sustain life. Understanding microbes helps us appreciate their vital contributions to health, environment, and industry.
