Question 9

longshore transport

Answer 9

transport of sand parallel to the coast

Question 10

types of breakers

Answer 10

spilling, plunging, and surging

Question 11

photosynthesis

Answer 11

CO2+H20+nutrients+light—->C6 H12 O6+O2
produces glucose and oxygen as a biproduct (phytoplanton go through this)

Question 12

respiration

Answer 12

C6 H12 O6 +O2 —> H2O +CO2 + nutrients+ energy
(zooplankton go through this)

Question 13

limitations of primary production

Answer 13

grazing, lack of light, and lack of nutrients

Question 14

what are examples of nutrients

Answer 14

nitrate, phosphate, silica, ammonium

Question 15

external sources of nutrients

Answer 15

can come from rivers, runoff, fertilizer, and dying animals
zooplankton produce nutrients

Question 16

major processes that control nutrient profiles

Answer 16

photosynthesis and respiration

Question 17

why are nutrients depleted at the surface

Answer 17

there is lots of photosynthesis at the surface because of the sun getting into the water column

Question 18

diatom

Answer 18

round looks like a lemon

Question 19

copepod

Answer 19

looks like a fish with no eyes

what is a plankton

Answer 20

it cant move itself so its movement is controlled by the tide

Question 21

phytoplankton

Answer 21

go through photosynthesis, primary producers

Question 22

main groups of zooplankton

Answer 22

holoplankton- plankton all the time
meroplankton-plankton for only part of their life

zooplankton

Answer 23

get energy through eating phytoplankton and respiration

Question 24

main groups of phytoplankton

Answer 24

diatoms
dinoflagellates

Question 25

plankton blooms
