Mutualism is an interaction where both species benefit. For example, lichen which is a mutualistic relationship between a fungus and photosynthesising algae or cyanobacteria. Fungi helps in absorption of nutrients and algae provides nutrition. Pollination is also an example of mutualism, where animals such as bees help in pollination and in turn the plant provides them with food. Barnacles and whales exhibit commensalism
