Prop. Sea Water
Bio - Properties of Sea Water & World Oceans
| Question | Answer |
|---|---|
| All Matter is Made of | Atoms |
| How many elements? | 118 (single type of atom) |
| Two or more atoms combined | Molecules |
| These types of bonds are weak in water | Hydrogen Bonds |
| Water does this when frozen into ice | Expands |
| What elements/compounds are in sea water? | Seawater & Dissolved Salt |
| What is seawater made of? | 96.5% water & 3.5% dissolved salts |
| What are the two main components of dissolved salt? | Sodium & Chloride |
| An evenly mixed mixture of dissolved components/parts | solution |
| This is always shifting between the atmosphere and the water on earth | Dissolved Oxygen |
| How does dissolved oxygen get "in" the water? | Photosynthesis - Air/Atmosphere |
| How does dissolved oxygen get "out" of the water? | Respiration - Air/Atmosphere |
| When there is MORE HEAT there is _____________ dissolved oxygen in the water | LESS |
| When there is MORE SALT there is _____________ dissolved oxygen in the water | LESS |
| Swimming heterotrophic organisms | Nekton (non-plankton element) |
| These are considered high trophic level carnivores | fish, squid, marine mammals |
| What lives in the benthos? | bottom-dwelling plants & animal that are sessile & mobile |
| Examples of Benthos creatures | crabs, mussels, worm, kelp, razor clams |
| Diatoms (phytoplankton) characteristics | silicates, carotenoids/chlorophyll, asexual, produce the air we breathe |
| How big are protozoa plankton? | 2mm-1mm |
| Characteristics of Protozoa Plankton | -single celled - shells & spines -shells called "tests" |
| Habitat of Protozoa Plankton | Ubiquitous; low productive ocean areas, in sediment & water column |
| Dinoflagellates characteristics | 2 flagella, cellulose, mostly marine, red tides, bioluminescence |
| What is a zooxanthellae? | a dinoflagellate in a symbiotic relationship with coral |
| This type of protozoa plankton is amoeba-like, has a skeletal structure or "shell", is 5um to >1mm, but has NO flagella or cilia | Sarcodines |
| These are knownn as "hole bearers" and have a calcareous shell and spine | Foraminifera -forams |
| These sarcodines have a siliceous shell and spine and thrive in Pacific equitorial | Radiolarians |
| These are the smallest protozoa plankton that have 2 flagella, they are covered in plates made of calcite, attribute to aclacerious sediments and can bloom in cold water | Coccolithophores |
| larval crustaceans, copepods, rotifers, jelly-like creatures are all considered _______________ | zooplankton |
| Shrimp, copepods and krill are all examples of what type of zooplankton | Crustaceans |
| These zooplankton have hair-like cilia for eating & moving, are reddish and tube-shaped home, and are filter feeders of dead materials, algae, bacteria, etc. | Rotifera |
