Question 1 of 20
What happens to the soil in agricultural lands near Balotra due to irrigation with chemical-laden water?
Question 2 of 20
Which of the following abiotic components acts as a direct structural link between the biotic and abiotic realms of an ecosystem?
Question 3 of 20
What is the primary role of the Bishnoi community mentioned in the context of the Great Indian Bustard?
Question 4 of 20
For REET candidates aiming to become educators, why is a profound understanding of ecology explicitly stated as 'non-negotiable'?
Question 5 of 20
Which of the following acts as the fuel for thousands of manufacturing units in Bhiwadi, contributing to pollution?
Question 6 of 20
A disastrous ecological consequence of rapid industrialization, which terrestrial forest biome globally consistently records the absolute highest rates of anthropogenic deforestation and structural fragmentation?
Question 7 of 20
Assertion (A): It is physically impossible for a stable ecosystem to feature an inverted Pyramid of Energy. Reason (R): The universal laws of thermodynamics dictate that energy is inevitably lost as metabolic heat at every successive trophic level.
Question 8 of 20
Which specific bacterium produces the neurotoxin causing Avian Botulism in Sambhar Lake?
Question 9 of 20
Assertion (A): The Wildlife Protection Act and Forest Conservation Act are essentially ecological management tools. Reason (R): These acts require a scientific understanding of ecosystems to effectively manage natural capital and drive sustainable development. Select the correct code:
Question 10 of 20
Regarding the distinction between a 'Habitat' and an 'Ecological Niche', consider the following statements: 1. A habitat is the physical geographic address of an organism. 2. An ecological niche represents the functional role or 'profession' of a species within the ecosystem. 3. Multiple distinct species can occupy the exact same ecological niche indefinitely without competition. Which of the statements given above are correct?
Question 11 of 20
What is the primary ecological consequence of a highly complex food web, as opposed to a simple, linear food chain?

Question 14 of 20
Which biome is explicitly noted as a prime example of a large regional ecological unit in the context of Rajasthan's environment?
Question 15 of 20
Which is the highest and most inclusive level of ecological organization that encompasses all life and ecosystems?
Question 16 of 20
Assertion (A): The flow of energy through an ecosystem's food chain is strictly unidirectional. Reason (R): As energy moves from producers to higher trophic levels, roughly 90% is dissipated into the environment as heat due to the laws of thermodynamics.
