Homework Answers
1. Bacterial flora of gut protects viral penetration through mucosa. certain bacteria protects us against flu. so it is for human benifit.
2. Microbes are nature's ultimate garbage disposal, they are so good that we use them to clean the sewage. so it is also benificial for us
3. Bacteria make food such as bread, beer, wine, vinegar, yoghurt, etc so they are useful in making food.
4. Nitrogen fixation- bacteria that fix nitrogen have symbiotic relationship with plants such as legumes. they are not directly helpful to human by fixing nitrogen.
ans=d. fix nitrogen
