definition symbiosis: Is a close relationship between two species
types of symbiosis:
Mutualism in this relationship both species benefit one another for example bees and flowers the flowers need the bees because they polonaise the flowers so that they can reproduce and the bees need the flower because the flower gives them nectar to make honey.
Commensalism in this relationship one species benefits and the other is not helped by no one but not harmed. like for example the a person cooks meal for someone and that person eats it the cooker is not getting harmed or helped but the consumer is getting helped.
parasitism in this relationship one species is benefited and the other is harmed for example mosquitoes and humans the mosquitoes bite humans and use blood for energy and humans get harmed because they can get a sickness.
