  1. Symbiotic Relationships

  2. Our goal for today is to answer these questions: • What is symbiosis? • What are the different kinds of symbiosis? • What are some examples of symbiosis?

  3. Symbiotic Relationships 3 Types of symbiosis: 1. Commensalism 2. Parasitism 3. Mutualism Symbiosis- two speciesliving together

  4. Symbiotic Relationships Commensalism- one species benefits and the other is neither harmed nor helped Ex. orchids on a tree Epiphytes: A plant, such as a tropical orchid or a bromeliad, that grows on another plant upon which it depends for mechanical support but not for nutrients. Also called xerophyte, air plant.

  5. Symbiotic Relationships Commensalism- one species benefits and the other is neither harmed nor helped Ex. polar bears and cyanobacteria

  6. Symbiotic Relationships Parasitism- one species benefits (parasite) and the other is harmed (host) • Parasite-Host relationship

  7. Symbiotic Relationships Parasitism- parasite-host Ex. lampreys, leeches, fleas, ticks, tapeworm

  8. Symbiotic Relationships Mutualism- beneficial to both species Ex. cleaning birds and cleaner shrimp

  9. Symbiotic Relationships Mutualism- beneficial to both species Ex. lichen

  11. Every organism has a habitat and a niche.

  12. A habitat differs from a niche. • A habitat is all aspects of the area in which an organism lives. • biotic factors • abiotic factors • An ecological niche includes all of the factors that a species needs to survive, stay healthy, and reproduce. • food • abiotic conditions • behavior

  13. Competition and predation are two important ways inwhich organisms interact. • Competition occurs when two organisms fight for thesame limited resource. • Intraspecificcompetition • Interspecificcompetition

  14. Predation occurs when one organism captures and eats another.
