Making of Nitrogen cycle 3d model for school science exhibition

INTRODUCTION

In this topic, we are going to show you how to build a Nitrogen cycle model for your science project or exhibitions.

Nitrogen cycle 3d model

Nitrogen Cycle and Its Stages

The nitrogen cycle is where nitrogen is converted into multiple chemical forms as it circulates through marine ecosystems, terrestrial and atmosphere.

Nitrogen cycle steps & Facts

Nitrogen Cycle conversion of nitrogen takes place both through a physical and biological process.

Nitrogen cycle mainly consists of nitrification, ammonification, denitrification, and fixation. 78% of the earth atmosphere is made up of nitrogen.

Nitrogen cycle consists of nitrogen fixation, Assimilation, Ammonification, Nitrification, Denitrification, nitrate reduction to ammonium, anaerobic ammonia oxidation and other processes.

Nitrogen Importance and Its Impact on Ecosystems

It has limited availability for biological use hence there is the scarcity of nitrogen in many types of ecosystems.

Availability of nitrogen can affect the rate of key ecosystem processes like decomposition and primary production.

Due to human activities like artificial nitrogen fertilizers, fossil fuel combustion and release of nitrogen in wastewater have changed the global nitrogen cycle.

It affects both natural environment system and also human health.

What are the Nitrogen forms?

Nitrogen is present in environment in various forms as ammonium, nitrate, organic nitrogen, nitrite, nitric oxide, nitrous oxide and inorganic nitrogen gas.

Organic nitrogen will be available in the form of a living organism and intermediate products of organic matter decomposition.

Benefits of Nitrogen Cycle

Nitrogen cycle helps to transform nitrogen from one form to another. This process is carried out by microbes to convert nitrogen to harvest energy or accumulate nitrogen from which can be used for their growth.

For example animal urine nitrogenous waste is broken down in the soil to be used by plants.

How to Make Nitrogen Cycle Model Step by Step Video

In this video, we will show you the following steps and items that can be used to build a nitrogen cycle model at home by taking help freely from your parents.

In this Nitrogen cycle, you will get to know the complete flow of the life cycle

  • how does nitrogen get into animals
  • how does nitrogen exit the atmosphere
  • how does nitrogen enter the plants
  • how does nitrogen exit the plants
  • how does nitrogen get into the soil

  • Blade
  • Pencil
  • Color paints
  • Paintbrush
  • Hot Glue Gun
  • Plastic animals
  • Fevicol
  • Waste Boxes to get cardboard
  • Scissor to Cut

Science Exhibition Questions & Answers on Nitrogen Cycle

  1. What are the stages of the nitrogen cycle?
    Stages of nitrogen cycle are: Nitrification, Assimilation, Nitrogen fixation, Ammonification and Denitrification.
  2. What is nitrogen cycle?
    Nitrogen cycle basically describes how nitrogen moves between plants, bacteria, animals, atmosphere, and soil. It is an important element on earth and it has to change into different states to be used by different life on earth.
  3. What are the types of the nitrogen cycle?
    Multiple chemical forms exist in the nitrogen cycle as it moves through the atmosphere, terrestrial and marine ecosystems.
  4. What is an example of the nitrogen cycle?
    Plants consume nitrogen from soil through roots. Nitrogen in the water undergoes through a process of fixation which is facilitated by bacteria named cyanobacteria.
  5. Why are nitrogen important humans?
    Nitrogen helps in the formation of amino acids in our body which in turn helps to make proteins.

Conclusions

Nitrogen cycle helps us to understand various forms of nitrogen and how it helps both human and other natural habitats.
