Symbiosis
•A type of close and long-term biological interaction between two different species. •Three types of symbiosis: 1.Commensalism 2.Parasitism 3.Mutualism Commensalism •A type of symbiosis occurring between individuals of two different species •One species obtains food or other benefits from the other without either harming or benefiting the latter. Commensalism (Ex.) •Remora and zebra shark – The remora attaches itself to the shark and rides along, saving its energy. •Cattle egrets and cattle – The cattle’s movements stir up insects on which the egrets feed. •Epiphytes are plants that grow on woody plants. They get nutrients from the air, so they only use the plant for support and access to the sun. Parasitism •A type of symbiosis occurring between individuals of two species. •One organism is harmful to the other but may not kill the other organism. •The organism being harmed is called the host. Parasitism (Ex.) •Pinworm – A small, thin, white roundworm that can negatively affect people. •Head Lice – A small, wingless, blood-sucking insect that lives in the hair and feeds off the scalp. •Scabies – A skin infestation caused by a mite, which causes a rash. Mutualism •A type of symbiosis occurring between individuals of two species •Each of the organisms benefits the other. Mutualism (Ex:) •Oxpeckers and zebras or rhinos – The birds live on the animal and eat all the bugs and parasites. •Flowers and bees – Bees get food and plants are pollinated. • Sea anemones and clownfish – Clownfish have a safe place to live and anemones are protected from their predators, the butterfly fish.
