Symbiotic Relationships

The three symbiotic relationships are parasitism, commensalism, and mutualism. Parasitism is when one organism will benefit from the other, and the other does not benefit and is harmed. For example when a human builds a new house, the humans benefit and get a new place to live. Then the animals that used to live there are harmed and no longer have that land. Commensalism is when one organism benefits and the other is not affected. When small fish swim around the big shark, the small fish receive protection and the shark does not receive anything. Mutualism is when both organism that are involved benefit. That way both are helped and they both gain something. For example when a bee pollinates a flower, the flower can reproduce and the bee has pollen. These all go on all around the world and that is why everything is why it is.
