Exploring Water Biomes - Characteristics and Ecosystems

1. Today is Wednesday, October 31, 2012 HOMEWORK: - Chapter 5 Homework Packet (due Monday, Nov. 5) “A Closer Look at Land Biomes” Worksheet (due Fri., Nov. 2) “A Closer Look at Water Biomes” Worksheet (due Mon., Nov. 5) Read Chapter 5, Lessons 5 and 6 (to be ready for class tomorrow) WARM UP: Please sit quietly and show me you are ready for some oral review (and deeper thought mind-teasers!!!!).

2. Shhhhhhhh!!!! • A little bit of review: • What is an ecosystem? All the living and non-living things in an area. • How is an ecosystem similar to your body’s digestive system? An ecosystem and your digestive system are made up of parts that work together to meet the needs of all parts. If one part of your digestive system fails, the rest of the system operates poorly. If one part of an ecosystem fails, the rest of the system operates poorly.

3. Review…..continued!!!!!!!!!!!!!!!!! • What might happen to the animals in a deciduous forest if Winter lasted year round? Some animals would have trouble surviving the continuous cold. The food and water available might not be enough to sustain all animals. • If no rain falls in a particular habitat for several years, how might the populations in the habitat reorganize themselves to remain balanced? Some organisms might leave the habitat because of less food or water. Other organisms might not survive.

4. Today’s Goal: • SWBAT demonstrate the ability to describe characteristics of different water biomes and ecosystems by completing a reference worksheet giving characteristics and pictures of each biome. • MAKE IT A DART-FREE DAY OR NOT….. • THE CHOICE IS YOURS!!!!!!!!!!

5. Water Biomes • The two true “Water Biomes” are: • Freshwater Biome • Saltwater (Marine) Biome

6. Within the fresh and salt water biomes, different ecosystems can be found: • Freshwater Biome: • Lake/Pond Ecosystem • River Ecosystem • Streams, brooks, true rivers • Wetland Ecosystem • Swamps, marshes, bogs, estuaries, sloughs

7. Saltwater Biome (Marine Biome): • Coral Reef Ecosystem • The “Rainforests of the Oceans” – most diverse water ecosystem!!!!!!!!!!!!!!!!!!!!!!! • Wetlands • Deep Sea Ecosystem • A journey into the great unknown…..we have better maps of some parts of the Moon than of some of the world’s ocean trenches

8. River Ecosystem River ecosystems have flowing water – generally freshwater Speed of flowing water varies Water temperatures vary from cold as ice (melting glacial streams) to warmer. Even warm rivers are usually cooler than standing water ecosystems Some coastal rivers may be brackish (i.e. saltwater/freshwater mix – like rivers around Shanghai) Plants and animals vary from river to river depending on water speed and temperature

9. Fish Atlantic Salmon – cold water Catfish – warm water Large Mouth Bass –warm to cool water

10. Beaver – warm to cold, but not tropical Water Snake – generally warmer water Red Spotted Newt – warmer water Snapping Turtle – warm water Crayfish – warmer water, but some can tolerate cool to cold water

11. Lamprey – cold water parasites!!!!!

12. Wetland Ecosystem • Ecosystem that is partly covered with water or is flooded at least part of each year. • Salt or Freshwater • Generally quite warm – but some are cold (cold Northern bogs) • Water is generally, but not always, slow moving or stagnate • Plant and animal life varies with temperature • -Ex. Florida Everglades, Swamps, Marshes, Estuaries, peat bogs in Ireland and the United Kingdom (cold)

13. Wetland Animals Deer – warm to cold Alligator - warm Frogs - warm to moderately cool Otter – warm to cold depending on species

14. Wetland Plants – warm to cool Emergent - Cattail Floating leaved Scrub Shrub - Buttonbush Submerged Floating Tree – Sycamore – this is a warm swamp

15. Mangrove swamps – tropical….hot!!Bring your towel to wipe off the sweat!!!!!!!SALT WATER

16. Coral Reef Ecosystem Coral reefs are the hard skeletal parts left from dead coral, the animal is the coral polyp inside Coral reefs are “The Rainforests of the Oceans” – most diverse aquatic ecosystem Coral reefs are tropical and sub-tropical only (WARM WATER!!!!!!!)

17. Coral Polyps Pineapple Coral Sun Coral

18. Coral Reef Different colors due to algae Table Reef

19. Clownfish and Sea Anemone

20. Deep Sea • Cold and dark; very high pressure (will smash you flat as a pancake) • Saltwater • NO LIGHT!!!!!!!! • “Marine Snow”

22. Gulper Eel • Jaw unhinged in order to swallow its prey whole • Grow 2-6 feet in length

23. Angler Fish - They are known for having a “fishing rod” that’s tipped with a fleshy bait, which is usually luminous

24. Viperfish • Sharp, fang-like teeth don’t even fit in its mouth, impaling its victims as it swims by at high speeds • Has light organs on its sides to attract smaller fish

25. Giant Tube Worms • Live near deep sea hydrothermal vents • They can grow up to 8 feet tall; some grow about 33 in/year

26. Giant Squid!!!!!

27. The world’s largest known living animal

28. Originally thought to have gone extinct 65 million years ago, this is one of the oldest known fish still living…. Coelacanth

29. Closing it up… • With your FACE PARTNER, discuss what you think the most awesome water ecosystem that we talked about today was.
