1 Symbiotic Relationships

2 SYMBIOTIC RELATIONSHIPS
1. SYMBIOSIS is the interaction between 2 different organisms living together HOST- usually the LARGER of the 2 organisms SYMBIONT- usually the SMALLER member

3 THE THREE SYMBIOTIC RELATIONSHIPS ARE...
Click on a Picture Below to Learn About the Relationship PARASITISM MUTUALISM COMMENSALISM EXTRA PRACTICE ACTIVITY GO BACK TO SPECIFIC QUESTION EXIT

4 PARASITISM - Is a relationship where the Symbiont lives in/on the Host
The Symbiont (or Parasite) BENEFITS and the Host is HARMED. (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 it loses the blood it needs to stay alive. EXIT

5 Mutualism - Is a relationship between the host and a symbiont, 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.) EXIT

6 COMMENSALISM - Is a relationship between the host and symbiont, 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. EXIT

7 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. EXIT

8 In this photo the “cleaner fish” receives nourishment by dining off of the parasites and remaining food debris in the eel’s mouth. Is this an example of… PARASITISM MUTUALISM COMMENSALISM HELP EXIT

9 PARASITISM MUTUALISM COMMENSALISM HELP EXIT
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 … PARASITISM MUTUALISM COMMENSALISM HELP EXIT

Lampreys are primitive fish with limited digestive systems. They attach to and feed on the body fluids of fish with more advanced digestive systems, often leading to the death of the host fish. This relationship is an example of… PARASITISM MUTUALISM COMMENSALISM HELP EXIT

Orchids grow on the branches of high trees. These orchids get more water and sunlight than those on the ground. The tree is unaffected by the orchid’s presence. This relationship is an example of… PARASITISM MUTUALISM COMMENSALISM EXIT HELP
