Answer:
Farmers are dependent on bacteria for their crops because bacteria play a crucial role in the soil ecosystem.
Step-by-step explanation:
Bacteria are responsible for breaking down organic matter, such as dead plants and animals, into nutrients that plants can use. Bacteria also help to convert nitrogen gas from the air into a form that plants can use, through a process called nitrogen fixation.
If farmers were able to remove all bacteria from the soil, it would have a devastating impact on crop growth. Without bacteria, organic matter in the soil would not decompose and release nutrients, leading to nutrient-poor soil. Additionally, without nitrogen-fixing bacteria, plants would not have access to the nitrogen they need to grow.
In short, the removal of bacteria from the soil would result in reduced crop yields, poor soil quality, and ultimately, threaten the food supply. Therefore, it is important for farmers to maintain a healthy soil ecosystem that supports the growth and development of their crops, including the bacteria that play an essential role in this ecosystem.
