An example of competition can be the competition of individuals of one species for food, territory. For example, a raven for food. An example of mutualism is the symbiosis of clown fish with sea anemones. At first, the fish slightly touches the sea anemone, allowing it to sting itself and finding out the exact composition of the mucus with which the sea anemone is covered – this mucus is needed by the sea anemone so that it does not sting itself. Then the clown fish reproduces this composition and after that it can hide from enemies among the tentacles of anemone. The clown fish takes care of the sea anemone – it ventilates the water and carries away undigested food debris.
