symbiotic
That is called commensalism.
It's called a parasitic relationship when one species benefits and one species is harmed. A simbiotic relationship is when both species benefit.
A relationship between one or more organisms which can be beneficial to each other, but not essentially so are called Symbiotic.The Symbiosis where one organism benefits, and one is unharmed, or unaffected is called commensalism.
A symbiotic relationship is one in which two organisms from different species interact.Take for example, the symbiotic relationship between a whale and the barnacles that live on the whale's skin. While the whale filter-feeds, it faces difficulties from the surrounding detritus that affects its vision in the water. Meanwhile, the barnacles get food in terms of the detritus the whale emits, and do not have to search for food. This is a mutualistic relationship, what one would call a 'win-win' relationship between organisms.There are five different kinds of symbiotic relationships:Mutualism, where both species benefitCommensalism, where one species benefits, the other is unaffectedParasitism, where one species benefits, the other is harmedCompetition, where neither species benefitsNeutralism, where both species are unaffected
Paracitism
Commensalism, in biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter. The commensal-the species that benefits from the association-may obtain nutrients, shelter, support, or locomotion from the host species, which is unaffected. The commensal relation is often between a larger host and a smaller commensal. The host organism is essentially unchanged by the interaction, whereas the commensal species may show great morphological adaptation. This relationship can be contrasted with mutualism, in which both species benefit.
In biology, a relationship between two species whereby one (the commensal) benefits from the association, whereas the other neither benefits nor suffers. For example, certain species of millipede and silverfish inhabit the nests of army ants and live by scavenging on the refuse of their hosts, but without affecting the ants.
The Difference between mutualism And commensalism is that mutualism is a relationship between two species in which both species benefit and Commensalism is a relationship between two organisms in which one organism benefits and the other is unnaffected.
The relationship between species in which one benefits at the expense of the other is parasitic. An example is a tick attaching itself to an animal and feeding from it.
they have mutuality relationship
Commensalism is where one species benefits and the other is unaffected. Like a bee and a flower. The bee benefits because it gets the nectar from the flower. The flower is unaffected because nothing happens to it.
On the face of it, the relationship does seem to be parasitic, but you must remember that:Parasitism is a type of symbiotic relationship between organisms of different species where one organism, the parasite, benefits at the expense of the host.(from Wikipedia)The mother benefits in the long term, because it is propagating the species.
