Since 2011, environment and ecology topics play a major role in the UPSC Prelims Exam. As per the trend analysis for the environment section of the UPSC prelims exam, anywhere between 10 to 20 questions are asked on average. As per the UPSC Prelims syllabus, General issues on Biodiversity, Climate Change, and Environmental ecology that do not need subject specialization are part of the environment section. Usually, candidates tend to neglect these subjects as they feel it is very easy. But this can result in scoring negative marks. A strong basic understanding of the Environment topics is enough to deal with the questions from the Environment and ecology segment.


Ecology is the study of organisms and how they interact with the environment around them. An ecologist studies the relationship between living things and their habitats. To learn about the natural world, ecologists must study multiple aspects of life ranging from the moss that grows on rocks to the wolf population in Yellowstone National Park.

DETAILS of Ecology

Ecology first began gaining popularity in the 1960s, when environmental issues were rising to the forefront of public awareness. Although scientists have been studying the natural world for centuries, ecology in the modern sense has only been around since the 19th century. Eventually, this led to the study of how animals interacted with plants, and other animals, and shaped the ecosystems in which they lived. Today, modern ecologists build on the data collected by their predecessors and continue to pass on information about the ecosystems around the world. The information they gather continues to affect the future of our planet. Human activity plays an important role in the health of ecosystems all around the world. Pollution emitted from fossil fuels or factories can contaminate the food supply for a species, potentially changing an entire food web. Introducing a new species from another part of the world into an unfamiliar environment can have unintended and negative impacts on local lifeforms. These kinds of organisms are called invasive species. Invasive species can be any form of living organism that is brought by humans to a new part of the world where they have no natural predators. The addition or subtraction of a single species from an ecosystem can create a domino effect on many others, whether that be from the spread of disease or overhunting.


The environment is included in the GS III paper in UPSC CS (Main) and in General Studies in Prelims. Since 2013, the Prelims for Indian Forest Services is combined with the UPSC Civil Services, which is why the weightage of the environment topic has increased. General Studies papers are asked about the environment topic, hence it is important to prepare them extremely well. Secondly, issues like global warming and climate change have become some of the major issues of the 21st century, hence, a thorough knowledge in this area would enable the potential bureaucrats to ensure they are able to implement their knowledge in policymaking. We’ve listed the micro-topics for environment and ecology for UPSC and also discussed the preparation strategy to effectively cover the syllabus.
