Answer:
B) Nitrogen-fixing bacteria and lightning
Explanation:
Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.
Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.
As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.
The lightning breaks nitrogen molecules and allow it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.
Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.
Answer:
Zero latitude
Explanation:
The difference is high is hotter and low is colder
Due to the abundant sunlight,
Suitable temperature
Excessive rainfall on a daily basis leads to flirtatious turnover of nutrients and plant growth is prompt.
Several factors affect the rate at which enzymatic concentration, substrate concentration, and the presence of any inhibitors or activators
If they are decreased at the same time and the same amount is being taken away from them at the same time then the gravitational force would stay the same but if they are be decreased one then the other they will go back and forth
