| Question | Answer |
|---|---|
| What is the relationship between temperature and salinity in a tide pool | as temperature goes up, salinity goes up (water evaporates leaving salt behind) |
| When a limped tries to attach itself to a rock, what is it trying to avoid? | desiccation - an animal drying out |
| Understand the feeding or organisms in the intertidal zone, lower and upper portions (easier or difficult in certain zones) | Lower tidal zone would have more food, water brings it in |
| Understand what a byssal thread is and what organisms produces them? | Something that mussels produce to attach themselves to a surface and to acquire food; Mussels |
| Abiotic and Biotic factors, which are the lower and upper limits? | abiotic regulate the upper limit, biotic regulate the lower limit |
| Know the variety of organisms and which zones has the most variety: upper, middle, or lower | Lower because thats the one thats under water the most |
| Muddy intertidal area, where would you find the most variety of organisms, near the surface or deep down in the mud? | Surface, mud doesn't have much oxygen production |
| According to most scientist when was the period that most estuaries were formed? | ice age |
| What is a sessile organism? | stays in one spot, lives at a given point |
| How does the salinity a sessile organism experience change throughout the day from high tide to low tide? | If the tide is in, it experiences more salinity, if the tide is out it experiences less salinity |
| Know what euryhaline means | Species that can tolerate a wide range of salinities |
| Know what stenohaline means | Species that cannot tolerate a wide range of salinities |
| Know what brackish water means | Mixed between fresh and salt water |
| Where are mangrove forests typically found? | tropical zone |
| Which mangrove have salt glands? | white mangroves |
| Which is more common in a mud flat? filter feeders or deposit feeders? | deposit feeders |
| What does coral growth require to survive? | 1. warm water, 2. sunlight, 3. hard substrate |
| Polyps connected by a thin layer of tissue, what is it called? | Coenosarc |
| Name two ways a coral can asexually reproduce | 1. budding, 2. grows upward and outward |
| Know how corals can obtain food | 1. can trap plankton or extend filaments to catch food particles, 2. Photosynthesis of the zooxanthellae |
| What is most likely the explanation for the formation of an atoll? | Started out as fringing reefs, that became a barrier reef and eventually turn into an atoll |
| If a coral has spicules, is it a stony or a soft coral? | only a soft coral produces spicules |
| Benthos, nekton, plankton | name which is where |
| Larval fish | plankton |
| Tuna | nekton |
| Lobster | benthos |
| Stingray | benthos |
| Manta ray | nekton |
| Jellyfish | plankton |
| If you're studying a soft-bottom shelf community in the tropics, what kind of sea grass will find there? | turtle grass |
| Do most organisms that would feed on a sea grass eat it when it is alive or after its died | after its died |
| Would you find seaweed in soft-bottom or hard-bottom substrate? | hard-bottom substrate, needs a hard substrate to attach to |
| Looking at non-reproductive cells from kelps from same species, despite being from the same species they have different chromosomes, how can that be? | Two generations, sporophyte and gameophyte |
