What do partners get (get) from a mutually beneficial relationship? Explain with a specific example.

Mutually beneficial relationships in biology are called symbiosis. Organisms in this relationship can provide each other with services such as cleanliness or protection, but most often help their partners find food. For example, marine invertebrates – anemones – protect the clown fish from predators with poisonous tentacles, and the fish instead cleans the anemones from dead organic particles. Mushrooms, entering into symbiosis with plants, deliver them water, and they themselves receive nutrients from them.
