Ken Larsen's website - Symbiosis
Symbiosis is a close relationship between two different kinds of living things.
There are six types of symbiotic relationships:
| Type | Explanation | Example |
| Predation | The preying of one animal on another like one animal consuming another. | Wolves hunting moose. |
| Parasitism | The parasite benefits; the host is harmed. About 40% of animal species are parasites. | |
| Competition | Two or more organisms rely on the same environmental resource. | |
| Mutualism | Both organisms benefit. | |
| Commensalism | One organism benefits; the other is not significantly harmed or helped. | |
| Herbivory | An animal consumes a producer or plant. |
