Notes on Environment(Natural Resources)
Q. 1. Explain with diagram the structure and function of environment?
Ans. Environment is a collective term for all the conditions in which an organism lives. It includes biotic and abiotic components whereas habitat is a place where an organism lives. The different components of environment are inter-linked and interdependent. [pic]
The organisms interact with physical environment composed of atmosphere, hydrosphere and lithosphere Environment is usually divided into two parts, physical and biotic. The physical environment consists of (i) forces of nature like wind and gravity (ii) conditions like temperature and light (iii) time and (iv) nonliving materials like soil and water. The biotic environment is made up of all living beings including their reactions, interactions and inter-related actions.

Q. 2. What is biosphere? Ans. Biosphere. The entire inhabiated part of earth and its atmosphere including the living components is called biosphere.
The three main sub-divisions of biosphere are hydrosphere, lithosphere and atmosphere.
1. Hydrosphere. It includes all the water components of oceans, seas, rivers and other inland water.
2. Lithosphere. It comprises the solid components of the earth’s crust which support life.
3. Atmosphere. It is formed of gaseous cover which envelops the hydrosphen and lithosphere.

Q. 3. What are the components of environment? Differentiate between the two. Ans. Components of environment.
1. Biotic components
2. Abiotic components
Difference between Biotic and Abiotic components

[pic] Q. 4. Define parabiosphere and eubiosphere. Give examples. Ans. Biosphere. It is the part of earth above and below the surface which support life is called biosphere. Biosphere is recognised as a combination of eubiosphere a parabiosphere. Parabiosphere. It is that part of biosphere which is not
