Zooplankton Ecology — Quiz

Test your understanding of zooplankton ecology with 5 practice questions.

Practice Questions

Question 1

What type of vertical migration involves ontogenetic shifts in depth habitat as zooplankton transition between life stages?

Question 2

If zooplankton ingest 200 mg C m^{-3} d^{-1}, have an assimilation efficiency of 70 %, and a growth efficiency of 40 %, what is their secondary production (mg C m^{-3} d^{-1})?

Question 3

What is the typical trophic transfer efficiency from phytoplankton to zooplankton in marine ecosystems?

Question 4

How does the presence of mineral ballast in zooplankton fecal pellets affect the efficiency of the biological carbon pump?

Question 5

Species A ingests 150 mg C m^{-3} d^{-1} with assimilation efficiency 60 % and growth efficiency 50 %; species B ingests 100 mg C m^{-3} d^{-1} with assimilation efficiency 80 % and growth efficiency 30 %. Which species has higher secondary production?
