Interspecific Interactions: Types, examples and study resources

📚 Quick Study Guide

• 🤝 Interspecific Interactions: Relationships between different species in an ecosystem.
• ➕ Mutualism (+,+): Both species benefit (e.g., bees and flowers). 🐝🌸
• ➖ Commensalism (+,0): One species benefits, the other is neither harmed nor helped (e.g., barnacles on whales). 🐳
• 😈 Parasitism (+,-): One species benefits, the other is harmed (e.g., ticks on dogs). 🐶
• 🦁 Predation (+,-): One species (predator) kills and eats the other (prey) (e.g., lions hunting zebras). 🦓
• 🌳 Competition (-,-): Both species are harmed by competing for the same resources (e.g., food, space).
• 🌿 Amensalism (0,-): One species is harmed, the other is unaffected (e.g., penicillin inhibiting bacteria). 🧪
