There are many examples of commensalism in a river. One example is a frog sitting on a lily pad because the frog can rest and eat on it without hurting it.
Observations of commensalism of plants may simply be the result of difficulties in identifying effects of the interaction on the "0" species (i.e. the species assumed to be unaffected). As in neutralism, one can not assert positively that there is no competition or benefit to either plant species.
Kangaroos and dung beetle Onthophagus have a commensalism relationship. The beetle live on the tail part of the kangaroo and feed on its dung. The kangaroo, on the other hand, makes use of the nitrogen containing compounds converted into proteins produced by the dung beetle.
The 3 types of symbiotic relationships (symbiosis) are: parasitism, mutualism, and commensalism. In parasitism, the organism known as the parasite impacts the life of the host dramatically, negatively damaging it as he benefits. In mutualism, both organisms living together benefit from the other in a cooperative relationship. In commensalism, the commensal benefits as the host is unaffected.
Parasitism-relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing it.Commensalism-a relation between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latterMutualism- association between organisms of two different species in which each is benefitedCompetition- utilization of the same resources by organisms of the same or of different species living together in a community, when the resources are not sufficient to fill the needs of all the organismsPredation-describes a biological interaction where a predator (an organism that is hunting) feeds on its prey, the organism that is attacked
Yes. River Song regenerated twice - once as a child, and once as Amy's friend 'Mel'. When Mel was injured, she regenerated into the version of River Song we first saw in Silence in the Library. However she gave her remaining regenerations up to save the Doctor, meaning her death in Forest of the Dead was her last, though her mind lives on inside CAL.
This type of relationship is commensalism. It is a type of symbiosis.

This is a form of symbiosis known as commensalism.
