Symbiosis refers to the close and long-term interactions between different biological species. There are three main types of symbiotic relationships:
-
Mutualism: In mutualistic relationships, both species benefit from the interaction. For example, in the video, bees and flowers were discussed as a classic example of mutualism. Bees pollinate flowers while collecting nectar, benefiting both the plants and the bees.
-
Commensalism: This type of relationship benefits one organism while the other is neither helped nor harmed. An example from the video is barnacles attaching to a whale. The barnacles gain a mode of transport and access to more feeding opportunities, while the whale is largely unaffected.
-
Parasitism: In parasitic relationships, one organism benefits at the expense of the other. The video mentioned a specific example of a tapeworm living in the intestines of a host organism, where the tapeworm absorbs nutrients, harming the host in the process.
