Symbiotic Relationship

Cattle egrets foraging in fields among cattle. The egret gets easy access to food and the cattle don't care if they are there or not.

• mutualism
• commensalism
• competition
• parasitism

Remoras are small fish that swim close to or attach themselves to sharks.  Remoras eat small scraps left as the sharks feed and the sharks are unaffected. 

• Competition
• Predation
• Mutualism
• Commensalism

A tapeworm and a dog have this type of relationship.

• mutualism
• parasitism
• commensalism
• competition

Barnacles create home sites by attaching themselves to whales. Since the barnacle is a filter feeder, it also gets access to more water (and food) due to the relationship. The whale is unaffected.
This is an example of which type of symbiosis?

• Commensalism
• Mutualism
• Parasitism
• Competition

Wrasse fish feed on the parasites found on the black sea bass's body (usually in the mouth). This is like dental floss for the fish and both species benefit.
This is an example of which type of symbiosis?

• Commensalism
• Mutualism
• Parasitism
• Predation

Ostriches and gazelles feed next to each other. They both watch for predators. Because the visual abilities of the two species are different, they can each identify threats that the other animal may not see as readily. Both species benefit.

Clown fish live among anemones, acting as a lure for the sea anemone's prey. The clown fish gets protection and shelter from the anemone.

Mistletoe extracts water and nutrients from the spruce tree to the detriment (ill effect) of the spruce.

Oxpecker birds feed on the ticks found on a rhinoceros. Both species benefit since the oxpecker gets food and the rhino gets rid of a parasite.
