Elimination Logic in Biogeography & Ecosystems

#5
Elimination Trick #5Associate unique natural-cultural features like Living Root Bridges with specific regions, particularly Northeast India.
#6
Elimination Trick #6Avoid assuming a plant's presence based solely on its general popularity; verify its specific ecological niche.

#8
Elimination Trick #8Avoid assuming all animals within a broad group (e.g., all bears) hibernate identically.
