Answer:

1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.

<em />

<em>The second question im not sure sorry- the positive and negative one ;(</em>

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.

5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.

6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.
