Where Do Germs Live? Everyday Examples of Microbe Habitats.

📚 Quick Study Guide

• 🦠 Germs are Everywhere: Microbes, including bacteria, viruses, fungi, and protozoa, are ubiquitous. They can survive in diverse environments.
• 💧 Moisture Matters: Germs thrive in moist environments such as bathrooms, kitchens, and damp surfaces.
• 🌡️ Temperature Range: Most germs prefer warm temperatures, but some can survive and even thrive in cold conditions.
• 🍎 Food Source: Microbes need nutrients to survive, so they are often found where food particles or organic matter are present.
• 👤 Human Contact: Frequent touching of surfaces can transfer germs. Handwashing is crucial to prevent this.
• 🧪 Survival Strategies: Some germs form spores to survive harsh conditions, allowing them to persist for extended periods.
