One of the most plentiful fossil fuel in the USA is coal, oil, and other natural gas are abundant right now and relativity inexpensive to drill or mine for.
Bacteria converts the ammonia and ammonium into nitrates and nitrites is described below.
Explanation:
1. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants. Denitrifying bacteria converts nitrates back to nitrogen gas.
2. The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter, Nitrospina, and Nitrococcus).
3. Nitrifying bacteria present in the soil convert ammonia into nitrite. Nitrite is then converted into nitrate. This process is called Nitrification.
4. De-Nitrification: Nitrogen in its nitrate form (NO3–) is converted back into atmospheric nitrogen gas (N2) by bacterial species such as Pseudomonas and Clostridium, usually in anaerobic conditions. These bacteria use nitrate as an electron acceptor instead of oxygen during respiration
In a tropical rain forest, the layer formed by the leafy tops of tall trees is called the Canopy and the layer of shorter trees and vine is called the Geographic range.
Answer:
Individuals that are well adapted to their environment will survive and reproduce
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Explanation:
Birds are thought to have evolved from dinosaurs. Through the study of the fossil record, scientists have discovered that some dinosaurs have similar anatomical features to birds. The fossil record shows that some dinosaurs have similar bone structure and some even have feathers.
The fossil record even shows that some dinosaurs display similar behaviours to birds like laying eggs in nests, incubating and caring for their young.
