Study Notes
Major Types of Species Interactions
- Five primary types: predation, competition, parasitism, mutualism, commensalism.
Predation
- Involves one organism (predator) killing and consuming another (prey).
- Examples: A lion hunting a zebra; hawks catching mice.
Competition
- Occurs when species vie for the same limited resources without direct contact.
- Examples: Plants competing for sunlight; animals competing for food.
Parasitism
- Involves a parasite living in or on a host and obtaining nutrients without immediately killing it.
- Examples: Ticks on mammals; tapeworms in intestines.
Mutualism
- A cooperative interaction where both species gain benefits.
- Examples: Bees pollinating flowers while feeding on nectar; clownfish providing protection for anemones.
Commensalism
- A relationship where one species benefits while the other is neither helped nor harmed.
- Examples: Barnacles attaching to whales; birds nesting in trees.
