Many aquatic organisms are cold-blooded so their bodies don't need to burn energy to stay warm. Which water property makes organism lose body heat 3 times faster in water than in air?
What is ... conduction.
30
Shallow, biodiverse biome enabled by a symbiotic relationship relationship of a photosynthetic algae living inside tiny animals.
What is ... coral reef
30
In this biome, the littoral zone is shallow w/ plants & the lentic zone is deep.
What is ... lake
40
This is the initial energy source that drive global air and water circulation patterns.
What is ... solar energy (strongest at equator)
40
Property of water that allows organisms, even very heavy ones, to float.
What is ... buoyancy
40
All organisms need this molecule to conduct respiration, so how much of it is available is a limiting factor for aquatic life.
What is ... dissolved oxgyen
40
Shallow, biodiverse marine habitat in cool waters off the coast of California. Main producer is very tall form of algae.
What is ... kelp forest
40
Invasive zebra mussels were introduced into this North American freshwater biome from ballast water.
What is ... the Great Lakes
50
It drives the movement of water through the atmosphere and causes mixing of surface water into deeper water in the ocean and lakes.
What is .... wind
50
Water's freezing point and boiling point in Celsius and Fahrenheit.
FP = 0C 32F BP = 100C 212F
50
The type and abundance of these benthic organisms is measured to assess stream health.
What are ... macroinvertebrates
(insects, insect larvae, clams, mussels, snails, crayfish etc.)
50
Shallow, tropical biome with tall-rooted plants that hold shoreline in place and give habitat to many organisms and their young.
What is .... mangrove
50
Freshwater biome that is lentic.
Freshwater biome that is lotic and well aerated.
Lentic = still = lake
Lotic = flowing (adds oxygen) = streams & rivers
60
A,B, and C in the hydrologic cycle.
A = evaporation B = runoff C = percolation
60
Water "reservoirs" that are the fastest and slowest to turnover or recharge.
choices: lakes, rivers & streams, oceans, atmosphere, groundwater
fastest = atmosphere (9d) slowest = ocean (3,000y)
60
Name of survey system using number, type, and health of fish to assess lake and river health.
What is ... Karr's Index of Biological Integrity

Four (4) shallow, marine habitats where organisms must be adapted to daily fluctuations in water level, salinity, light and temperatures.
What are ... intertidal zone, saltwater marsh, mangrove, estuary.
60
Eutrophication of this biome results from nutrient (N&P) overload that initially increases producer numbers, followed by producer die-off & decay that depletes the system of dissolved oxygen, causing fish die offs.
What is ... lake (but also happens in gulfs & bays)
