Question
Chapter 38, Problem 9WIO
Summary Introduction
To determine:
The changes that would happen if there is no bacteria in the body and also determine the changes in nutrient cycle without bacteria.
Concept introduction:
It is known that human body has several friendly bacteria. These bacteria play some important roles in the human body. Nutrient cycle is the movement of organic and inorganic matter back into the production. In nutrient cycle, the energy moves in unidirectional pathway.

Answer the riddle.
We are microorganisms. We are selfless. We make the environment conducive for our other siblings to grow at the expense of our life. Add us to food and we can positively transform it. But don’t be too happy because some of us can spoil it. Name us.
Fill in the blanks. In the Nitrogen cycle,
into
are responsible for converting
denitrifying bacteria/ammonium and ammonia/atmospheric nitrogen
O nitrifying bacteria/ammonium and ammonia/nitrites and nitrates
nitrogen-fixing bacteria/ammonium and ammonia/atmospheric nitrogen
Onitrogen-fixing bacteria/ammonium and ammonia/nitrites and nitrates
