• Prevent extinction and maintain balance

🧪 Important Formulas & Classifications

🔸 Plant Classification Rule:

• Dicots = 2 cotyledons + Reticulate venation + Taproot
• Monocots = 1 cotyledon + Parallel venation + Fibrous root

🔸 Habitat Types:

• Terrestrial = Land habitats
• Aquatic = Water habitats
• Amphibians = Both land and water
