Study Notes
Species Interactions
- A community encompasses all living organisms within a specific area.
- Organisms within communities constantly interact, significantly impacting the ecosystem.
Types of Species Interactions
- Competition: Occurs when organisms (same or different species) vie for the same resources (food, water, light, nesting sites, or space) in the same location and time.
- Predation: One organism (predator) hunts and consumes another (prey). The predator kills and eats the prey.
- Symbiosis: A close, long-term relationship between two different species.
- Mutualism: Both species benefit from the relationship. Examples: Flowers and insects, where flowers provide nectar and insects spread pollen. Hippos and birds, where birds eat insects on hippos' backs.
- Commensalism: One species benefits, while the other is neither harmed nor helped. Example: Triggerfish and smaller fish, where the triggerfish moves rocks for smaller fish to feed. Barnacles and whales, where barnacles benefit from the constant water flow around whales.
- Parasitism: One species (parasite) benefits, while the other (host) is harmed. The parasite obtains nutrition from the host. Example: Some bacteria, protists, and intestinal worms like tapeworms. External parasites like ticks, fleas and lice.
Competition Details
- Competition can result in a winner and a loser. The winner thrives, and the loser may struggle or perish.
- Resources are anything essential for survival: food, water, shelter, etc.
Predation Details
- Predation is a powerful force in communities, defining relationships in food webs and regulating population sizes.
- Predators have adaptations (e.g., sharp teeth, claws, acute senses) that enhance their hunting success.
- Prey species have adaptations (e.g., camouflage, speed, poison) to avoid being caught.
Mimicry
- Mimicry is a form of deception used by prey to avoid predators.
- A harmless species mimics a harmful or distasteful species.
- Examples: King snakes mimicking poisonous coral snakes, viceroy butterflies mimicking monarch butterflies.
Plants and Herbivores
- Herbivores are animals that eat plants.
- Adaptations: Plants develop defenses (e.g., thorns, spines, bad taste) to deter herbivores from eating them.
Predator-Prey Examples
- Notes are provided in a table format
Symbiotic Relationships
- Symbiosis is a close, long-term relationship between organisms of different species.
- Details of each relationship type listed above
Parasites
- Parasites are organisms that live on or in a host organism, benefiting from the host while harming it.
- Ectoparasites: Live on the exterior of their host. Examples: Fleas, ticks, lice, and leeches.
- Endoparasites: Live within their host. Examples: Tapeworms, some bacteria, and some protists.
