Communities and Interactions

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

Which is an example of intraspecific competition

• 2 types of bacteria competing for food

• Food

• Water

• Shelter
