Study Notes
Community Interactions Review
- Relationship harming one species: A relationship where one species benefits, and the other is harmed, is called parasitism.
- Predator-prey relationship: A frog eating a fly is an example of a predator-prey relationship.
- Relationship benefiting both species: A relationship where both species benefit is called mutualism. An example is the crocodile and bird, where the bird cleans the crocodile's teeth and the bird gets food and protection.
- Relationship benefiting one, other unharmed: A relationship where one species benefits, and the other is not harmed or benefited, is called commensalism. For example, a decorator crab camouflaging itself with sponges, with the sponges unaffected is an example of commensalism.
- Competition for resources: When two species compete for the same resources, one can eventually go extinct.
- Resource partitioning: When two species divide a resource based on behavioral or physical differences is resource partitioning. Examples of resource partitioning include different species of lemur eating different parts of bamboo.
- Species occupying the same niche: No two species can occupy the same niche.
- Specialists vs Generalists: Specialist species have a narrow range of food, habitat, and other environmental conditions versus generalist species that can eat a variety of food and survive in different environments.
- Predation is eating energy: Predation is when one animals eats another for energy.
- Symbiosis: A close relationship between two organisms is called symbiosis.
- Parasitism: Parasitism is when one species benefits from another species that is harmed. Tapeworms in a host are an example of parasitism.
- Endoparasites: Parasites that live inside a host's body.
- Ectoparasites: Parasites that live outside a host's body.
- Mutualism: When both organisms benefit.
- Competition: Two or more organisms trying to use the same resources
- Competitive exclusion: If two species try to occupy the same niche, one might go extinct.
- Character displacement: One species evolves physical characteristics to reduce competition.
- Symbiotic relationship: A close interaction between two organisms is symbiotic.
- Food web: Multiple species interacting in a close relationship.
