"Microbes, also known as microorganisms, are tiny living entities too small to be seen. They can exist as single cells or form complex colonies, inhabiting nearly every environment on Earth, including soil, water, air, and within other living things. Microbes are fundamental to life, playing a crucial role in shaping the planet’s environment. They are essential for processes that sustain all other life forms, from nutrient cycling to oxygen production." 🦠🦠
