Question

Q NO 3: what is nitrification, dentrification, ammonification and nitrogen cycle?​

Answer 1

Answer:

Explanation: Ammonification: This is a process where bacteria or other decomposers break down nitrogen-containing chemicals from waste or a dead body into simpler chemicals, such as ammonia. Nitrification The plants are able to take in nitrates from the soil.  

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmosphere nitrogen, making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

$\sim$ $\huge\underline\mathcal {Nitrification}$

$\implies$The process by which bacteria in soil and water oxidize ammonia and ammonium ions and form nitrites and nitrates. Because the nitrates can be absorbed by more complex organisms, as by the roots of green plants, nitrification is an important step in the nitrogen cycle.

$\sim$ $\huge\underline\mathcal {Denitrification}$

$\implies$Denitrification is the microbial process of reducing nitrate and nitrite to gaseous forms of nitrogen, principally nitrous oxide (N2O) and nitrogen (N2). A large range of microorganims can denitrify. Denitrification is a response to changes in the oxygen (O2) concentration of their immediate environment.

$\sim$ $\huge\underline\mathcal {Ammonification}$

$\implies$Ammonification. When a plant or animal dies or an animal expels waste, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium (NH + 4), a process called ammonification or mineralization.

$\implies$The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine .
