  1. Symbiosis: I get by with a little help from my friends…. OBJECTIVE: Identify Different Interactions among species

  2. Symbiosis Definitions • Habitat: The ecosystem in which an organism lives.

  3. Symbiosis Definitions • Niche: Full range of physical and biological conditions in which an organism lives and the way the organism uses those conditions.

  4. Symbiosis Definitions • A Niche Includes: • Food: What the organism eats, how it’s obtained, where is it on the food web? What eats it? • Abiotic Conditions: Non-living things needed to survive (sun, temperature, water, salt water, fresh water, heat, protection, etc.) • Behavior: When and how it reproduces, mating rituals, hibernation, defense mechanisms, different parts of the tree

  5. Symbiosis Definitions • How is a niche different from a habitat? VS

  6. Symbiosis definitions • Competition: When organisms attempt to use an ecological resource at the same time in the same place.

  7. Symbiosis definitions • Competitive Exclusion Principle: Two species competing for the same resources cannot coexist if other ecological factors are constant. • When one species has even the slightest advantage or edge over another, the one with the advantage will dominate in the long term. • Behavioral shift, or evolutional shift to a different niche.

  8. Symbiosis definitions • Predation: When one organism captures and eats another organism.

  9. Symbiosis Definitions • SYMBIOSIS is the interaction between 2 different organisms living together • HOST- usually the LARGER of the 2 organisms • SYMBIONT- usually the SMALLER member

  10. Mutualism • Is a relationship between the host and a symbiont, where both organisms benefit and neither is harmed. • The relationship can be long or short term. • For example, the host flower benefits by being pollinated by the traveling butterfly. The symbiont butterfly benefits from the nectar that it extracts from the flower.

  11. Commensalism • Is a relationship between the host and symbiont, where the symbiont benefits and the host is neither helped nor harmed. • The symbiont benefits by receiving transportation, housing, and/or nutrition. • For example, barnacles receive transportation from the host whale. The host whale is neither helped nor harmed by the barnacles.

  12. Parasitism • Is a relationship where the Symbiont lives in/on the Host • The Symbiont (or Parasite) BENEFITS • The Host is HARMED • For example, the tick in the picture above is a parasite. It benefits by extracting blood from its human host. The human is harmed because

  13. Symbiosis in nature • Write the partner, what happens in the relationship, and then identify the relationship as • Parasitism, • Mutualism, or • Commensalism

  14. Whale and the… Barnacle Barnacles attach themselves to whales and filter feed as whales swim through the water. This is an example of: COMMENSALISM

  15. Rhinoceros and the… Oxpecker Oxpeckers eat ticks on the rhinoceros’s back. This is an example of: MUTUALISM

  16. Maribou stork and the… bee Stork cuts up dead animals that it eats with its beak. Bees lay eggs on the carcasses that provide food for the eggs. This is an example of: COMMENSALISM

  17. Mouse and the… Flea Fleas live on the mouse and eats its blood. This is an example of: PARASITISM

  18. GAZELLE AND THE… OSTRICH Feed next to each other and warn each other when predators come. This is an example of: MUTUALISM

  19. BISON AND THE… COWBIRD Cowbird follows the bison and eats the insects in the grass. This is an example of: COMMENSALISM

  20. Deer and the… Tick Live on deer and suck their blood. This is an example of: PARASITISM

  21. Black sea bass and the… Wrasse fish Wrasse fish eats parasites on black sea bass. This is an example of: MUTUALISM

  22. Shark and the… remora Attaches to shark and eats scraps from the shark’s meal. This is an example of: COMMENSALISM

  23. SPRUCE TREE AND THE… MISTLETOE Mistletoe grows on spruce trees and uses its water and nutrients. This is an example of: PARASITISM

  24. YUCCA MOTH AND THE… YUCCA Yucca moth pollinates yucca plant and lays its eggs on the flower. This is an example of: MUTUALISM

  25. WARBLER AND THE… CUCKOO Attaches to shark and eats scraps from the shark’s meal. This is an example of: PARASITISM http://www.youtube.com/watch?v=dAU5MTXmAPY http://www.arkive.org/cuckoo/cuculus-canorus/video-09c.html

  26. BADGER AND THE… HONEYGUIDE BIRD Attaches to shark and eats scraps from the shark’s meal. This is an example of: MUTUALISM http://www.youtube.com/watch?v=D544WoTj5qI

  27. Nile crockodile and the… Plover Plovers clean the teeth of the crocodile without danger. This is an example of: MUTUALISM

  28. Clownfish and the…. Sea anenome Clownfish feeds on animals which could harm the sea anenome, and the sea anenome gets nutrients from clown fish waste. This is an example of: MUTUALISM
