Examples of symbiotic relationships in nature.

📚 Quick Study Guide

• 🤝 Symbiosis: A close and long-term interaction between two different biological species.
• 🌱 Mutualism: A symbiotic relationship where both species benefit. Example: Bees pollinating flowers.
• паразитизм Parasitism: A symbiotic relationship where one species benefits and the other is harmed. Example: Ticks on dogs.
• 🏡 Commensalism: A symbiotic relationship where one species benefits and the other is neither harmed nor helped. Example: Barnacles on whales.
• 🍄 Mycorrhizae: A mutualistic association between a fungus and the roots of a plant. The fungus helps the plant absorb nutrients from the soil, and the plant provides the fungus with carbohydrates.
• 🐟 Cleaner Fish: Small fish that eat parasites off larger fish. This is a mutualistic relationship.
• 🦠 Gut Microbiota: Many animals, including humans, have bacteria in their digestive systems that help them digest food. This is another example of mutualism.
