The nitrogen cycle is
a repeating cycle of processes during which nitrogen moves through both living and non-living things
: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms.
What is nitrogen cycle 9 short answer?
Nitrogen cycle
The sequence in which nitrogen passes from the atmosphere to the soil and organisms, and then is eventually released back into the atmosphere
, is called nitrogen cycle. It is a process by which atmospheric nitrogen is converted into the form which can be easily absorbed the organisms on earth.
What is nitrogen cycle in Class 8?
Nitrogen cycle is
all about the movement of nitrogen between various elements on Earth
(like air, soil, living organisms etc.) The amount of nitrogen in the atmosphere remains constant.
What is nitrogen cycle in easy English?
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. … Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
What is a nitrogen easy definition?
: a nonmetallic chemical element that under standard conditions is
a colorless, odorless, inert gas
, that constitutes 78 percent of the Earth’s atmosphere, and that is used especially in the industrial synthesis of ammonia, as a component of inert atmospheres, and in liquid form as a refrigerant — see Chemical Elements …
What is nitrogen cycle explain with diagram Class 9?
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
. … Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
What is nitrogen fixation class 8 short?
The process of converting Nitrogen in the air to Nitrogen compounds
which can be used by plants is called Nitrogen Fixation.
What are protozoa Class 8?
Protozoa: These are
unicellular microscopic organisms similar to animals
that can move about to capture food and are heterotrophic in nature. They are mostly aquatic in nature. Amoeba, paramecium are some examples of protozoa.
Why the nitrogen cycle is important?
Nitrogen is
a crucially important component for all life
. … It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
What is nitrogen cycle and its importance?
“Nitrogen Cycle is
a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms
.” Furthermore, nitrogen is a key nutrient element for plants. However, the abundant nitrogen in the atmosphere cannot be used directly by plants or animals.
What is nitrogen cycle explain with diagram?
Hint: This cycle is a
biogeochemical process through which nitrogen is converted into many forms
, consecutively passing from the atmosphere to the soil to the organism and back to the atmosphere. Complete answer: Nitrogen undergoes various sorts of transformation to take care of a balance within the ecosystem.
How do humans affect the nitrogen cycle?
Many human activities have a significant impact on the nitrogen cycle.
Burning fossil fuels, application of nitrogen-based fertilizers, and other activities
can dramatically increase the amount of biologically available nitrogen in an ecosystem.
How does the nitrogen cycle start?
The nitrogen cycle is a chain of biological reactions that produces chemical results. It begins
when decaying food and fish waste produce ammonia
.
What is nitrogen an example of?
An allotrope of an element pertains to any of the multiple substances formed by only one type of element. Examples of
allotropes
of nitrogen are atomic nitrogen and dinitrogen. Atomic nitrogen (active nitrogen) is a very reactive allotrope of oxygen.
How can you describe nitrogen?
Nitrogen, or N, using its scientific abbreviation, is
a colorless, odorless element
. Nitrogen is in the soil under our feet, in the water we drink, and in the air we breathe. In fact, nitrogen is the most abundant element in Earth’s atmosphere: approximately 78% of the atmosphere is nitrogen!
