biotic interactions
Competition: The activity or condition of competing for a resource.
Predation: The preying of one animal on others.
Symbiosis: Interaction between two different organisms living in close physical association, typically to the advantage of both.
Mutualism: Symbiosis that is beneficial to both organisms involved.
Commensalism: An association between two organisms in which one benefits and the other derives neither benefit nor harm.
Parasitism: A non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host.

examples:
An example of mutualism would be the oxpecker and zebra. The oxpeckers land on zebras to feed off of ticks and parasites. The oxpeckers obtain a source of food from this, and the zebras don't have to deal with the parasitic organisms.
An example of commensalism would be barnacles. Barnacles attach themselves to rocks, whales, boats, etc. They obtain a place to stay protected and reproduce, while the receiver of the barnacles doesn't get anything in return. An example of parasitism is leeches. Leeches feed off of blood and usually live in wet places such as lakes, ponds, rivers, etc. They obtain a source of food from the host, but hurt them in the process. |
