Sea bass |
|
Tuna fish, dolphins and penguins have teardrop shaped bodies. This and other adaptations exhibited by marine organisms that swim rapidly, efficiently and for sustained periods. |
*general shape shared by a wide variety of nektonic organisms that require sustained efficient swimming *major advantage over other shapes is that is has much less drag because water flows over with less turbulence. *the dolphin is a mammal and penguin is a bird, so both are homeotherms and can maintain higher metabolic rates because of their higher body temperature. Although most fish are cold-blooded, large Tunas like the bluefin can maintain elevated body temperatures because a counter current blood flow through their muscles captures and retains heat. Elevated body temperature contributes to more efficient swimming in all three *other adaptations discussed pertain particular to the Tunas and billfish especially and include secretion of mucus or oil that reduces friction and drag, indentation to allow fins to lie flat against the body, reduced scallion and skin that indents to reduce turbulent eddies. |

List 6 kingdoms of life and give examples |
1) Archaea: thermophilic, methaogenic and other extremophiles prokaryotes 2) Bacteria: the "true" bacteria including staph, strep, cyanobacteria, and most of the heterotrophic marine bacteria. 3) Protista: diatoms, dinoflagellates, red green, and brown algaes, foraminifera. 4) Fungi: mold, mildew, yeasts, mushroom 5) Plantae: mosses, ferns, vascular plants 6) animals: sponges, jellyfish, worms, mollusk, arthropods, chordates. |
|
Primary production |
It is called primary because it is the way food is manufactured at the base of all food chains. Photosynthesis is the major mechanism of primary production, but some bacteria carry out chemosynthesis. |
|
Explain limiting factor |
Any factor such as temperature, light, and salinity that limits the survival of organisms |
|
Photosynthesis |
Light energy is captured by chlorophyll and used to manufacture sugars -primarily glucose- from simple molecules of carbon dioxide and water. (Also produces oxygen) |
|
Diatoms |
One of the most abundant and efficient of the oceans primary producers and are among the organisms at the lowest tropic level in the food Web that ultimately leads to the tunas |
|
Picoplankton |
They are prokaryotes and their taxonomy is debated. Many such as synechococcus, seem to be cyanobacteria. Account for up to 70% of the primary production in some ocean regions. |
|
General patterns of primary production in temperate ocean. |
* the seasonal changes of temperate oceans produces a characteristic pattern of productivity. *strengthens during summer, weakening during fall *water is well mixed and nutrients are brought into the photic zone in the fall and mixing is strong throughout winter. *sunlight increases in the spring and couples with the already-present nutrients there is a bloom of phytoplankton. |
|
8 invertebrate phyla |
Porifera (sponges) Cnidaria (sea anemones, jellyfish, etc) Platyhelminthes (flatworms) Nematoda (roundworms) Annelida (segmented worms) Mollusca (clams, snails, and octopus) Arthropods (shrimps, crabs, and lobsters) Echinodermata (sea stars, sea urchins, etc) |
|
Characteristics of the intertidal zone |
Part of the shore alternately exposed and submerged by water. Animals living there are exposed to wave stress, desiccation, exposed to air, rapid changes in temperature and salinity, and ultraviolet radiation from the sun. |
|
Animals in the intertidal zone |
The most diversity of animal types. Crabs and fishes can move with the changing water levels, staying mostly in the lower intertidal and hiding in crevices and under rocks. Barnacles and mussels are attached to rocks and cannot move, so they close their shells until the water returns. |
|
Two types of primitive chordates |
Tunicates and amphioxus |
|
Tunicates |
Feed by filtering suspended material from the water through their system |
