What is paleobotony and what significance does this field have to our understanding of plants?

Paleobotany is a branch of the paleontology and the paleobiology. Its main focus are the recovering and identification of the plant remains (the plant fossils) found into the geologic contexts.

The paleobotany is a very important branch as it is the one that gives us the answers about the emergence of the plants, their evolution and development over time. Also, it gives us answers how the plants from the past lived, what was the environment in which they existed, their needs, and how the plants influenced the environment around them.

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.
