UPSC Preparation: Introduction to Environment and Ecology

The preparation process the for Civil Services Examination (CSE) is lengthy, dynamic and challenging in nature. There is a lot to learn in a relatively short period of time. Imagine how helpful it would be if only the key points are presented to you from the significant topics of the CSE syllabus? Thanks to the High Yield Series videos from Unacademy as it accomplishes the above mentioned goal: Learning more in a less period of time. 

 

The High Yield Series constitutes the Environment and Ecology (EnE) portion of the CSE syllabus which has been carrying a heavy weightage of marks in the recent years. The major topics of the EnE portion are as follows: Ecology, Ecosystem structure and function, Ecological succession, Population interaction, Biodiversity, IUCN Red Data Book, Biomes, Interaction, Energy Flow, Nutrient Cycle, Ecological Pyramids, Ecosystem services etc. It is highly imperative to familiarise oneself with the terminologies of the Environment and Ecology portion in order to gain better clarity of the concepts discussed.

In the video titled “UPSC IAS: High Yield Series: Environment and Ecology Part 1.1”, Dr. Roman Saini deals with various aspects of the Environment and Ecology portion of Civil Services Examination Preparation. Dr. Roman provides an introduction to Environment and Ecology (EnE) and discusses about the major topics in EnE, terminologies, graphical representation of major biomes (where x-axis is mean annual precipitation and y-axis is mean annual temperature), list of abiotic factors, different responses of various organisms to these abiotic factors, definition of adaptation, its various examples and finally explains in detail the population pyramids.
