Presentation Transcript

  1. Image Explain: In the , find 3-4 errors with this food web, and describe how to fix them. Warm Up:

  2. During which years is the population of willow trees growing exponentially? • 2. What is the carrying capacity of this population? • 3. What kind of graph is shown when a population reaches its carrying capacity? Warm Up – TUESDAY SPOT • 4. Explain why a population cannot grow exponentially forever.

  3. Predator-Prey Interactions

  4. Predation (pg 778) Definition: An interaction in which one organism hunts then eats another • PREDATOR – the organism doing the eating • PREY – the organism getting eaten

  5. Predation: Not Predation:

  6. “Boom – Bust” Population Cycle • Some populations increase rapidly and then decrease rapidly • THINK ABOUT IT…. • Describe why a predator – prey interaction usually results in a boom-bust cycle (BOOM) (BUST)

  7. Predator ADAPTATIONS: Things that help them find and capture prey easier • Speed / Agility • Coloring • Team up in packs • Acute senses • Claws, teeth, fangs, stingers

  8. Prey ADAPTATIONS Things that help them avoid getting eaten • Retreat to safety • Flee quickly • Camouflage • Warning coloration • Mimicry

  9. Symbiotic Relationships (pg 780) • Definition: A close interaction between two species in which one of the species lives in, on or near the other.

  10. Parasitism One organism benefits, the other is harmed • Examples: • Tapeworm • Mosquito • Fleas/ticks • Sea Lamprey • Bacteria

  11. Mutualism Both organisms benefit from the interaction • Examples: • Bee and flower • Crocodile and Plover • Oxpecker and Zebra

  12. Commensalism One organism benefits, the other is neither helped nor harmed • Examples: • Fringed toed lizard and rat • Moss and tree • Barnacle and whale

  13. Symbiosis Image Explain • What kind of relationship is this? (MUTUALISM, COMMENSALISM OR PARASITISM?) • Who benefits? • How can you tell?

  14. Symbiotic – Crab Example • Read the article and determine what type of relationship is shown. • How can you tell? BRAIN POP!!!
