Why are stone tools so important to archaeologists

La elaboración de las primeras herramientas de piedra fue determinante. Permitió que los primeros representantes del género Homo consiguieran adaptarse al medio ambiente en el que habitaban y consiguieran una explotación de recursos más eficiente.

En sí son importantes porque tienen historia y nos pueden mostrar por medios de estudios para que se llegaron a utilizar

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.
