Bacteria are required or needed in the nitrogen cycle because other living properties cannot use atmospheric nitrogen.
<h3>What is the nitrogen cycle?</h3>
The nitrogen cycle is the sequence of operations by which nitrogen and its mixtures are interconverted in the environment.
In living organisms, It considers nitrogen fixation and pollution.
As regards Nitrogen fixation is affected, just bacteria are competent to improve atmospheric nitrogen into structures usable by other living organisms.
In nitrogen fixation, the atomic nitrogen is converted into chemical forms functional by plants and convert atmospheric nitrogen into chemical forms functional by plants.
Therefore, option A is correct.

Answer:
Glaciers cause erosion by plucking and abrasion. Valley glaciers form several unique features through erosion, including cirques, arêtes, and horns. Glaciers deposit their sediment when they melt. Landforms deposited by glaciers include drumlins, kettle lakes, and eskers.
Explanation:
The correct answer is B. Cells divide, producing more cells.
Explanation
The cell is the basic unit of life for all living things. Likewise, it is a form of classification for them since living organisms can be classified according to the number of cells they have unicellular (a single cell), multicellular (more than one cell). In organisms that have more than one cell, they divide to produce more cells and form the organs and tissues themselves. Cell division can occur from two processes that are mitosis and meiosis in which two and four cells are produced respectively. According to the above, the correct answer is B. Cells divide and producing more cells.
