Ecotones are the transitional zones between two ecosystem.

Explanation:

Ecotones is a narrow zone between two different ecosystem.

It may be defined as the transition zone between these two ecosystem. Ecotones are species rich and it's resources are used by inhabitants of both the ecosystem.

Ecotones are marked by sharp changes in vegetation and species population.

The ecotones arise due the drastic changes in the environmental condition of a place that creates a sharp boundary between it and adjacent area.

However, these changes blend somewhere in between these  area and results in formation of ecotones.

Example of ecotones can be the mangroves. These lie between marine ecosystem and terrestrial ecosystem.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
