Symbiotic Relationships are relationships between two creatures that in some way help each other out. For example the clown fish and the sea anemone. The clown fish eats small fish or invertebrates that may hurt the anemone and in return the anemone give the clown fish a home in its poisonous stingers, in which the clown fish are immune to but other fishes aren't. If the clown fish was not immune to the sea anemone then the invertebrates and the bacteria would get to the anemone and kill all the anemones in the ocean. Also the clown fish would not have a home to live or somewhere to be safe from there predators and also the clown fish would not have his food supply so the clown fish would also die.
Another symbiotic relationship is humans and vegetables. The vegetables grow a produce food for us, and we plant more seeds for the plant to reproduce. if us humans did not plant more seeds after we picked them would mean that we would run out of supply of vegetables, which would cause us to become unhealthy. Also animals the animals that eat those vegetable would die if they did not have there food, so eventually we would run out of supply of food.
Bearded Dragons do not have a symbiotic relationship with anything.
