| Oceanic Crust- | The portion of the earths’ crust that primarily contains basalt, is relatively dense, and is about 5 kilometers thick |
| Continental crust | The portion of the earths’ crust that primarily contains granite, is less dense than oceanic crust, and is 20 to 50 kilometers thick |
| Top layer of the ocean | surface layer, well mixed |
| thermocline | transitional zone between warmer and colder layers of ocean |
| deep layer | thick and cold |
| Respiration | The process by which food is converted into useable energy for life functions |
| Osmosis | The diffusion of water across a selectively permeable membrane. |
| Endotherm | An animal whose internal body temperature is a result of internal sources of heat. |
| Poikilotherm | An organism whose body temperature changes with its surrounding environment |
| Ectotherm | An organism whose body temperature is controlled by its surrounding environment. |
| Homeotherm | An animal that maintains a controlled internal body temperature using its own heating and cooling mechanisms. |
| Name of genetic information transfering from generation to generation | heredity |
| Multiple organisms of the same species coexisting together | population |
| Ornate, silica cell walls, one or two flagella and many small chloroplasts | silicoflagellates |
| unicellular, have many round, chalk-like plates called coocoliths | coccolithophores |
| Holoplankton | Spends entire life as plankton |
| Meroplankton | Only larval stage as plankton |
| Pigments that color Rhodophyta's algae | phycobilins |
| Cyanobacteria can perform... | nitrogen fixation |
| mangroves have... | prop roots |
| Amoebocytes | Cells within a sponge that produce its skeletal structure, perform digestion, and repair cell damage |
| Cindarians' stinging structures | nematocysts |
| Sea fans, sea plumes, sea pens, sea anemones are from class _______ | Anthozoa |
| Gemmule | A group of cells surrounded by a shell made of spicules |
| Chitin | A derivative of carbohydrates that provides |
| Carapace | An armored shield that covers the anterior portion of crustaceans |
| Why can cephalopods move easily? | Because their shell is on the inside, and they can take water into the mantle cavity and shoot it out, making themselves propel |
| What does a shark use to keep itself afloat and why? | It uses its large, oily liver and it stays afloat because oil and water counteract with eachother |
| A bony fish uses what to keep itself afloat? | It uses its air bladder and can control how far up and down it is in the water column. |
| Baleen | Rows of comb-like plates that project from the upper jaws of filter-feeding whales. |
| How long is the gestation for most cetaceans (whales)? | About a year |
| What are two differences between order Sirenia and order Cetacea? | Sirenia have large, paddle like tails and live only in warm, shallow water. Cetacea have flukes on their tails and live in almost any water. |
| 3 things happen during a marine mammals deep dive. what are they? | 1. the oxygen supply is increased and oxygen consumption is decreased 2. the heart rate slows and blood only flows to vital parts of the body. 3. the rib cage collapses and air is forced out of the lungs |
| What form nitrogen form is used most? | Nitrates |
| Primary productivity measures concentration of | organic carbon |
| Organisms that live on the bottom are called | Benthic organisms |
| Organisms that live in the water column away from the bottom | Pelagic organisms |
| Interspecific competition | Competition between two different species for the same resource |
| Intraspecific competition | Competition between organisms of the same species for the same resource |
| Name 3 ways carbon can be dissolved into the air | Respiration from producers, respiration from consumers and the work of decomposers |
