|---|---|---|---|---|---|
| What is plankton? | Drifting or weakly swimming organisms suspended in water
🗑
|
||||
| What connects plankton in categories? | an ecological connection; size of organism
🗑
|
||||
| What research vessel carried out the first large-scale plankton study? | Meteor 1925-1926
🗑
|
||||
| What is included in a quantitative analysis of plankton? | an estimate of the sampled volume of water and a count of the the organisms
🗑
|
||||
| What is required to study very small plankton? | the concentration of water samples by centrifugation or entrapment by a filter
🗑
|
||||
| Why are phytoplankton critical for marine life? | They bind to at least 35 billion metric tons of carbons into carbohydrates ; contribution to food webs and their generation of large amounts of atmospheric oxygen through photosynthesis
🗑
|
||||
| Which plankton are considered microplankton? | diatoms, dinoflagellates, and invertebrate larvae
🗑
|
||||
| What is the smallest form of plankton? | femtoplankton
🗑
|
||||
| What planktonic group accounts for 80% of all photosynthesis in the tropics? | picoplankton
🗑
|
||||
| What is a microecosystem? | A community operating on the smallest possible scale
🗑
|
||||
| What is the most productive photosynthetic plankton apart from Cyanobacteria? | diatoms
🗑
|
||||
| What is a frustule? | A reference to the patterns of perforations through the diatom's rigid cell walls
🗑
|
||||
| What makes light absorption in diatoms more effective than just using chlorophyll? | accessory pigments
🗑
|
||||
| What allows diatoms to expand in size during reproduction? | the auxospore
🗑
|
||||
| What photosynthetic organism is found in the tissues of coral? | dinoflagellates
🗑
|
||||
| What is usually responsible for a harmful algal bloom? | species of dinoflagellates
🗑
|
||||
| A highly biological productive ocean surface appears chalky; what plankton is likely successful here? | coccolithophores
🗑
|
||||
| What do researchers use to directly measure the rate of productivity? | carbon-14
🗑
|
||||
| What new method(s) is/are being used to calculate productivity by estimating the chlorophyll? | remote sensing and orbiting satellites
🗑
|
||||
| What is essential in the restoration and continuation of photosynthetic productivity in the ocean? | upwelling
🗑
|
||||
| What can hinder photosynthetic productivity in the open ocean? | iron ; minerals and light
🗑
|
||||
| Why is photosynthesis inhibited at the very top layer of the ocean surface? | too much light
🗑
|
||||
| What is true of compensation depth? | -usually corresponds to te depth to which about 1% of surface light penetrates -marks the bottom of the euphotic zone changes with sun-angle, turbidity, surface turbulence, and other factors -production equals consumption
🗑
|
||||
| What changes the compensation depth? | sun-angle, turbidity, surface turbulence, and other factors
🗑
|
||||
| Where is phytoplankton the most productive? | near the continents or the temperate zone
🗑
|
||||
| What season does phytoplankton peak in the northern temperate zone? | fall
🗑
|
||||
| What is the most abundant larger zooplankton? | copepods
🗑
|
||||
| What kind of plankton remains planktonic for its entire life? | holoplankton
🗑
|
||||
| What Zooplankton is considered a keystone species? | krill
🗑
|
||||
| What is created due to the decomposition of falling biological debris and zooplankton activity? | oxygen minimum zone
🗑
