Answer:
Different groups of bacteria help in the cycling of nitrogen , carbon and phosphorus by chemical fixing or releasing in environment.
Explanation:The ecosystem contains flow of energy and cycling of minerals.
In the cycling of minerals, the micro-organisms help in fixing atmospheric nutrients e.g., nitrogen fixation by some bacteria and release the nutrients to the environment by decomposition of organic matters.

Explanation:
Peripheral tissues receive oxygenated blood via the circulatory system. Delivering oxygen to cells, oxygen diffuses through tissues along a gradient of high to low amounts. Thus, option B is correct.
<h3>What is the movement of oxygen in cell?</h3>
Hemoglobin and oxygen interact chemically inside the red blood cell, where it is carried both by free diffusion and hemoglobin-facilitated diffusion. In blood plasma, oxygen is transferred by free diffusion and convection through cell membranes.
Therefore, The concentration of oxygen will be lower inside the cell compared to outside the cell.
