Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your
