Warm Up #6.57. You are given enough funds and resources to save one type of biome (out of the 11 we have discussed in class). Which biome would you save? In a paragraph (at least 5-6 sentences) provide at three reasons or more on why you would save this one over any of the others.

Warm Up #6.57
  • You are given enough funds and resources to save one type of biome (out of the 11 we have discussed in class).

Which biome would you save? In a paragraph (at least 5-6 sentences) provide at three reasons or more on why you would save this one over any of the others.

type 1 coastal zone
Type 1: Coastal Zone
  • Shallow salt water
  • Close to shore
  • Light-rich, nutrient poor
  • Biodiversity
  • Threatened by human activity
importance of ocean currents
Importance of Ocean Currents
  • Upwelling – cycling of warm surface water with cool deep water
    • Nutrient cycling
    • Aquatic – Phytoplankton and whales
el nino
El Nino
  • El Nino Southern Oscillation (ENSO) – in Pacific Ocean
  • Western winds weaken
    • Occurs every 3-4 years
    • Lasts several months
  • Result: no nutrient upwelling, dramatic affects aquatic ecosystems
coral reefs
Coral Reefs
  • Tropical forests of the sea
    • Near equator, biodiversity, nutrient poor water
  • Coral = keystone species – affect many other organisms of ecosystem
  • Coral and algae = mutualism relationship
coral and algae a case study
Coral and Algae: A Case Study
  • Algae live inside coral

+ = algae make food (photosynthesis)

+ = coral protect and provide nutrient-rich enviro.

  • Nutrients make coral skeleton (calcium carbonate)
    • Regulates CO2 levels

Coral and Algae cont’d
  • Algae = temperature and salinity sensitive (limiting factor)
  • Human activity = high temps
  • Result: algae die  Coral Bleaching – coral turns white, releases CO2
effects of coral bleaching
Effects of Coral Bleaching
  • Loss of biodiversity
  • Loss of tourism (Great Barrier Reef) – less $$
  • Raised ocean temps (CO2) – positive feedback
  • More invasive, harmful species

Quick Quiz # pi
  • Why are coral considered to be a keystone species?
  • Use two specific examples to explain why coral and algae have a mutualism relationship?
  • Why is coral bleaching an example of a positive feedback event?
