Symbiotic Relationships Quiz

Symbiosis Overview

• Symbiosis refers to interactions between two different species.
• There are five main types of symbiotic relationships: mutualism, commensalism, parasitism, predation, and competition.

Mutualism

• Both species benefit from the relationship.
• Example: Clownfish find protection within an anemone while attracting food for the anemone through their presence.
• Some relationships, like pollination, can be considered mutualistic or commensalistic depending on context.

Commensalism

• One species benefits while the other remains unaffected.
• Example: Carmine Bee Eaters may benefit from their relationship with other species without harming those species.

Parasitism

• One organism benefits at the expense of the other, causing harm.
• Example: Head lice feed on the scalp, harming the host.
• Example: Mistletoe parasitizes trees, drawing nutrients and harming them.

Predation

• Involves one species using another as a food source.
• This relationship results in the death of one of the organisms involved.

Competition

• Occurs when organisms vie for the same limited resources, lowering each other's fitness.
• Resources include food, water, space, and mates.
• Individuals competing for the same resources ultimately do not benefit.
