AIIMS 2018 Botany Mass Extinctions MCQ Question

Asteroid collisions are widely recognized as significant contributors to mass extinction events due to their potential to cause catastrophic environmental changes, such as wildfires, tsunamis, and a "nuclear winter" effect from dust and debris blocking sunlight. This leads to a dramatic decline in photosynthesis, severely disrupting ecosystems and food chains. Other potential causes, such as volcanic eruptions or climate change, may also play a role, but they are often considered secondary to the immediate and devastating impact of an asteroid collision. Understanding these dynamics is crucial for comprehending the complex interactions that can lead to widespread biodiversity loss.
