SYMBIOSIS

We've been studying about the relationship between animals from different species. Here you have the video we saw in class so you can revise these concepts:

- PARASITISM: the parasite benefits while the host is harmed.

- COMMENSALISM: one species benefits while the other is neither harmed nor helped.

- MUTUALISIM: both species benefit from the relationship.
