What was the main cause of the death of flamingo chicks?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Increase in the salinity of water.
Explanation: The passage states, “Zooplanktons, algae and the small fish that these birds survive on are dying due to a sudden increase in the salinity of the Rann waters.” This led to lack of food, causing adult flamingoes to flee and abandon their chicks, resulting in their death.
Predatory animals are mentioned as a threat, but not the cause here.
Dams caused the salinity to rise, but the immediate cause was salinity itself.
Inhospitable terrain affects study efforts, not the birds' survival directly.
Final Statement: The direct cause of chick death was the food shortage caused by increased salinity.
Conclusion: The correct answer is Increase in the salinity of water.
