Question

What is the role of bacteria in the food web and what would happen if there were no bacteria present in the food web?

Answer 1

Bacteria helps degrade dead animals and plants and bring valuable nutrients back to Earth ,it is also vital in keeping nitrogen cycling through the ecosystem, and nitrogen is vital to plant growth. If there were no bacteria present in the food web , animals that rely on it to digest their food would start dying off.

Answer 2

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.
