Introduction An ecosystem is a functional unit of the environment. Here living organisms interact among themselves and also with their surrounding physical environment. Grassland is an ecosystem where various types of organisms, plant species, and many microorganisms live. These ecosystems can be observed somewhere in every corner of the globe. All of these grasslands are

Introduction The biogeochemical cycle is an important cycle in the biological world. As the name suggests biogeochemical cycles cannot be completed without living beings hence organisms are also deeply dependent on this cycle. The nitrogen cycle is one of the most important biogeochemical cycles of all the cycles. It is an essential element and it

Introduction Grassland biotic factors are the living component of this region, it is called grassland because it is covered by grass. About 20% of the earth’s surface is covered by grassland, this region belongs to the terrestrial ecosystem. Grasslands are developed in the central part of the continent where the average annual rainfall is 90

Introduction The atmosphere is the only source of nitrogen with a total amount of about 78%. The nitrification process is one of the steps of the nitrogen cycle. This nitrogen is the most essential element for all living organisms. This nitrogen circulates from the atmosphere to the biosphere and again from the biosphere to the

Introduction Plants adapt accordingly in different regions of the world due to changes in climate and natural diversity. They change and maintain their existence through the process of reproduction. Due to continuous adaption, there is a series of continuous and orderly changes in a plant community can be observed. This sequential change of plants is
Introduction Earth is a very diverse planet with various species. Hence is composed of both living and non-living things. The source and quantity of all these substances on earth are fixed. All living things like viruses, bacteria, plants, animals, and the human body are composed of basic elements. All these elements have been circulating in
