Study Notes
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.
