Carolus Linnaeus

Explanation:

The formal system of classification was introduced by a Swiss scientist named Carolus Linnaeus.

He first split living things into a general category called KINGDOM.

- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).

- Each phylum or division is broken down into CLASSES.

- Each class is broken down into ORDERS

- Orders into FAMILIES,

- Families into GENUS

- Genus into SPECIES

Thus, the linnaean system of classification from highest (most general category) to the lowest level is as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species.

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.
