Mutualism
Crocdylus niloticus and the Pluvianus aegyptius
The Nile crocodile and the egyptian plover bird have a mutualistic relationship in which the plover bird cleans the crocodile's teeth after the crocodile eats. In doing so, the plover bird eats any excess food, completing its diet, and the crocodile has a mouth less vulnerable to cavities and infections. Both of the organisms benefit, displaying mutualism.

Parasitism
Plasmodium falciparum and Homo sapiens
Malaria is a parasite that is transmitted by mosquitoes. It is transmitted to the host, humans, when mosquitoes suck the blood out of them. Malaria enters the host and uses it as a feeding ground and reproduces inside the blood cells. The parasite reproduces in the cells and then eventually the cell bursts and they move to new cells. In doing so, the host may be fatally injured as it causes problems in the liver and its cells are being attacked, but the parasite benefits from this relationship.

Commensalism
Spilopelia senegalensis and Phoenix dactylifera
Laughing doves live in palm trees. The tree provides a habitat for the dove and the tree is not harmed in any way.
