Answer:
Bacteria are essential for life. They play a crucial role in all ecosystems, from the soil to the ocean floor. Without them, we could not survive. If we did not have bacteria, then our bodies would be sterile—we would die before we even reached adulthood. Many scientists believe that without bacteria, most life on Earth would cease to exist because they break down organic materials into simpler substances. This helps plants grow, which eventually creates oxygen.
Along with this, many important chemicals are produced by bacteria, including vitamin K, vitamins A, C, D, E, and B12; as well as minerals such as iron and magnesium. In addition, some antibiotics are derived from bacteria. Without bacteria, our ecosystem would collapse.
