EOSC 315 Final Exam Questions and
Answers 100% Verified

What 2 things control phytoplankton variability - Answer- 1. sunlight
2. nutrient availability (macro and micro)

when are phytoplankton considered light limited - Answer- when they cannot increase
their total biomass and support high levels of productivity

What are 2 issues with light in the ocean for organisms - Answer- 1. water absorbs and
reflects light (less light intensity)
2. organisms inconsistent position within the mixed layer = inconsistent light exposure

Photic zone depth depends on what 4 things - Answer- 1. season (deepest in summer,
shallow in winter)
2. weather (deepest when sunny, shallow when cloudy)
3. amount of particles in water (deepest when clear)
4. amount of phytoplankton (deeper with less)

self shading effect of phytoplankton - Answer- large concentrations of phytoplankton at
the surface reduce amount of light reaching phytoplankton living at deeper depths

2 things thermocline is affected by - Answer- 1. heating from sun (warm water less
dense)
2. wind mixing (storms)

describe temp profile of temperate ecosystem when:
sun heats surface ocean, winds decrease
sun energy decreases, winds increase - Answer- ML develops, stronger thermocline
ML weakens, weaker thermocline

SST can very from _____ to _____ - Answer- -2 C
>32 C

when the ML is deeper there is ______ nutrients supplied from the deep - Answer- more

2 things limiting phytoplankton in spring - Answer- 1. light - arch of sun and daylight per
day
2. depth of ML - can be too deep for photosynthesis

,compensation depth - Answer- PS = R (at a fixed point)
depth at which the photosynthetic and respirational processes of the phytoplankton
community existing at that depth balance each other
growth of phytoplankton stays the same

critical depth - Answer- depth above which total photosynthetic production (of everything
above) is equivalent to total respiration per unit of surface area
phytoplankton do not grow beneath critical depth

T or F - phytoplankton grow beneath the critical depth - Answer- False
do not grow beneath - light limited

phytoplankton are _____ limited in the winter and _______ limited in the summer -
Answer- light
nutrient

seasonal variation of PP ______ in temperate ecosystems (compared to tropics) -
Answer- high

temperature profile of temperate ecosystem during:
winter
spring
summer
fall - Answer- winter - deep thermocline, no ML (straight line)
spring - ML slighter shallower
summer - shallow ML (most intense thermocline)
fall - same as spring

nitrate profile of temperate ecosystem during:
winter
spring
summer
fall - Answer- winter - straight line, high surface concentration
spring - same as temp but opposite direction
summer - low surface concentration, same as temp but opposite
fall - deepening ML, possible bloom (medium surface concentration)

in temperate region in winter the ML is _______ than the critical depth. What does that
mean for phytoplankton - Answer- deeper
light limited

ML is deeper when there is _____ solar heating at surface - Answer- less

reason for spring bloom in temperate zones - Answer- shallow ML (longer days)
high nutrients (from winter mixing)

, ML is ______ in summer temperate regions, and phytoplankton are _______ limited -
Answer- shallow
nutrient

ML is _________ in fall temperate regions, and there is ______ nutrients due to more
wind mixing - Answer- deeper
increasing

in areas of coastal upwelling there are more or less nutrients and more or less sinking
detritus - Answer- more
more
opposite in non-upwelling coastal area

an area of upwelling will have a high _________ concentration - Answer- chlorophyll

what does upwelling do to surface water - Answer- increases nutrients at surface -->
extends bloom

uptake of 3 main nutrients by phytoplankton - Answer- N (nitrate), P (phosphate), and
sometimes Si
during photosynthesis becomes organic matter

general structure of a nutrient profile in temperate zone - Answer- start depleted at
surface (0) then increase to a point then decrease slightly

photosynthesis is the ________ of nutrients, respiration is the _________ - Answer-
uptake
release

2 ways organic matter is broken down - Answer- 1. dissolution - chemical processes
2. bacterial respiration - biological processes

most limiting nutrient in the ocean - Answer- N

Pacific or Atlantic more likely to be Si limited. why? - Answer- Atlantic
younger water

T or F - areas of the temperate continental shelf still have high productivity compared to
open ocean - Answer- True

why do nutrients increase in the fall (temperate zone) - Answer- no PS (light limited)
taking up nutrients
deeper mixed layer
