  1. LIS Quiz I Review

  2. 32. Adaptation • Ability for an organism to change/adjust to its surroundings

  3. How do LIS Abiotic Factors affect Plant/Animal Adaptations?

  4. Salinity • In a salt marsh, salt tends to concentrate as the water evaporates during low tide. • Glasswort– stores water (moisture) in leaves or stems - so the plant does not dry out and die. (tastes salty)

  5. Salinity • In the Sound if levels are too high or too low fish have the ability to move to better suited conditions

  6. Tides At Low Tide: • Worms must bury in sand • Crabs hide under rocks • Crab coloring helps to camouflage with rocks

  7. Tides As Tide Comes In: • Barnacles have ability to attach themselves to rocks or shells in order to “hold on”

  8. Sunlight • Periwinkles (Snails) gather at low tide on the lower half of the rocks and below seaweed where it remains moist and out of the direct sun.

  9. Soil • Dune grass has deeply ribbed blades so they can catch sand blown by the wind, causing it to fall to the base of the plant, creating its own “dune”. (Holding the grass in place)

  10. The Race • Low Energy Shoreline • Estuary • Intertidal Zone • Tidal Flat • Salt Marsh • Benefits of a Wetland

  11. LIS Animals • Zooplankton • Worm • Snail • Crab, Spider Crab, Lobster • Barnacle, Clam, Oyster • Striped Bass • Seagull & Heron • Seal • Human • Benthos • Water Column • Carnivore • Herbivore • Omnivore • Sessile • Filter Feeder

  12. Density • Formula • Show work with units • Density of Water

  13. Density Examples • Block A has a volume of 100ml and a mass of 50g. Find the density of Block A and decide if it will sink or float in water – explain why. • Block B has a volume of 5ml and a mass of 10g. Find the density of Block B and decide if it will sink or float in water – explain why. **Be sure to show all work and units!**

  14. Answers to Density Examples Block A: D= M/V D= 50g/100ml D = .5g/ml Block A – will float because it is less dense than water which has a density of 1g/ml Block B: D=M/V D = 10g/5ml D= 2g/ml Block B – will sink because it is more dense that water which has a density of 1g/ml

  15. 4. Salinity • Fresh Water • Brackish Water • Salt Water

  16. (Back of Flashcard) • Salt Content – how much Salt (NaCl) is in something • Salt Water / Ocean Water 35 ppt & over • Takes more energy to boil and to freeze • Densest • Brackish Water – less than 35ppt but greater than .5ppt mixture of fresh & salt – LIS • Fresh Water – less than .5ppt – little dissolved material – Rivers, Streams,

  17. SaltWater • Salt water is made during the movement of water over land as it dissolves solid salt crystals in rock.

  18. What is pH?Know Acidic, Neutral, and Basic Ranges on Scale
