What are the relationships between these species called? SYMBIOSIS!
Symbiosis comes in many forms • http: //www. youtube. com/watch? v=Z 5 t. Yey. Ch FB 0
symbiosis
Types of symbiosis: 1. Predation Predator captures, kills & consumes prey 2. Parasitism One organism harmed other benefits. Use of a host 3. Competition Result of a niche overlap. Same limited resource by two or more species
Types of symbiosis: 4. Commensalism One benefits and the other neither benefits or is harmed 5. Mutualism Both organisms benefit
Mimicry one is“Ifthe coral snake? The. Which old saying… redpoisonous touches black, you’re ok Jack. If red touches yellow, you’re a dead fellow. ” Antipredator defense • Which one is the mimic? • A harmless species seemingly poisonous or Coral Snake Scarlet King Snake dangerous
