Exam 14: Plankton, Algae, and Plants

What kind of plankton remains planktonic for its entire life?

What research vessel carried out the first large-scale plankton study?

What planktonic group accounts for 80% of all photosynthesis in the tropics?

Measuring biomass is not efficient in calculating primary productivity because dense areas can have lower productivity.

Coccolithophores are able to utilize more frequencies of light so they can be deeper in the euphotic zone and need less light.

What season does phytoplankton peak in the northern temperate zone?

What is a frustule?

What allows diatoms to expand in size during reproduction?

What is the most abundant larger zooplankton?

The addition of iron into ocean waters could drastically change the climate by allowing more carbon dioxide from the atmosphere to be bound into carbohydrates via photosynthesis.

Dinoflagellates have a deeper compensation depth than diatoms.

Approximately 55% of the sunlight energy absorbed by diatoms is converted into energy for carbohydrate chemical bonds.

What can hinder photosynthetic productivity in the open ocean?

Seaweed derived materials are found in a large variety of commercial materials including adhesives, salad dressing, and ice cream.

A highly biological productive ocean surface appears chalky; what plankton is likely successful here?

Consumption in phytoplankton usually exceeds carbohydrate production which is why we end up with oxygen.

What do researchers use to directly measure the rate of productivity?

Seaweeds are not a type of plant.

What changes the compensation depth?

What are seaweeds? What are the classifications of seaweeds?
