PARASITISM
Is a relationship where the parasite HARMS the host
For example, the tick in the picture above is a parasite. It benefits by extracting blood from its human host. The human is harmed because
EXIT
Is a relationship between two species, where both organisms benefit and neither is harmed.
The relationship can be long or short term.
For example, in the photo above, the host flower benefits by being pollinated by the traveling butterfly. The symbiont butterfly benefits from the nectar that it extracts from the flower.
Mutualism
EXIT
COMMENSALISM
Is a relationship two species, where the symbiont benefits and the host is neither helped nor harmed.
The symbiont benefits by receiving transportation, housing, and/or nutrition.
For example, in the photo above the symbiont barnacles receive transportation from the host whale. The host whale is neither helped nor harmed by the barnacles.

EXTRA PRACTICE ACTIVITY
In the following activity, you will be given a picture scenario. Identify and select the symbiotic relationship (parasitism, mutualism, or commensalism) represented in the picture.

Clownfish are frequently found in the tentacles of sea anemones. Sea anemones capture their prey by paralyzing them with their tentacles. However, the clownfish produces a mucus that prevents the tentacles from harming it. By dwelling amongst the tentacles the clownfish receives a protected home. This relationship is an example of …
