- Which of the following is NOT a plankton?
- jellyfish
- copepod
- boat shaped diatom
- sea anemone
- Which of the following are not members of the phytoplankton?
- diatoms
- coccolithophores
- silicoflagellates
- none of the above
- The dominant phytoplankton from the polar zone are the:
- diatoms.
- coccolithophores.
- radiolarians.
- dinoflagellates.
- Dinoflagellates obtain their nourishment by:
- photosynthesis.
- the direct ingestion of organic material.
- chemosynthesis.
- A and B
- Zooplankton are:
- herbivores.
- carnivores.
- omnivores.
- A, B, or C
- Blue whales feed mainly on:
- copepods.
- krill.
- chaetognaths.
- foraminiferans.
- Phytoplankton cells are autotrophic. This means they:
- make their own food.
- move independently of each other.
- require normal salinity.
- require sunlight.
- A rapid increase in phytoplankton population that can discolor the water is called a:
- growth spurt.
- bloom.
- explosion.
- expansion.
- Some phytoplankton have whip-like appendages called ______that are used for limited mobility.
- tails
- wings
- swooshes
- flagella
- Jellyfish are members of a group of animals called:
- Cnidaria.
- Tintinnids.
- Ctenophores.
- Chaetognaths.
- Zooplankton that spend only a portion of their lives as plankton are called:
- holoplankton.
- meroplankton.
- benthoplankton.
- ctenoplankton.
- Which of the following organisms spend a portion of their lives as plankton?
- snails
- barnacles
- starfish
- crabs
- All of the above are correct.
- The most numerous organisms in the oceans are the:
- nekton.
- phytoplankton.
- benthos.
- zooplankton.
- bacteria.
- A toxic algal bloom caused by dinoflagellates is often mistaken for blood in the water. Another name for this phenomenon is:
- green floods.
- red tides.
- brown pools.
- blue slicks.
- A jellyfish is an example of:
- phytoplankton.
- bacterioplankton.
- zooplankton.
- viroplankton.
- Which of the following is not a common example of a marine phytoplankton?
- jellyfish
- diatom
- green algae
- radiolarian
- Marine phytoplankton are responsible for primary productivity globally. What do you think this means?
- These organisms spend a lot of time eating each other
- They create a lot of energy through photosynthesis
- They spend most of their time in the tropics
- They are the top of the food chain
- All zooplankton are:
- heterotrophs.
- autotrophs.
- meroplankton.
- holoplankton.
- Which of the following is an example of meroplankton?
- Portuguese-man-of-war
- Pteropod
- Crab larvae
- Copepod
- Which type of phytoplankton causes diatomaceous earth?
- dinoflagellates
- diatoms
- radiolarians
- cyanobacteria
- From the Sponge Bob episodes we watched explain why the character plankton and the jellyfish do not meet the qualifications of being plankton. Do not use examples like they cannot talk or they do not wear clothes.
- From the size categories below explain where the Sponge Bob character plankton should probably fit and why you think so. Then put where the jellyfish should fit and why you think so.
Picoplankton
Nanoplankton
Microplankton
Macroplankton
Megaplankton
- From the plankton classification activity describe why the plankton were put only the top portion of the ocean on the watershed mural and what that zone is called.
