Biology

Question 1

heterotrophs

Answer 1

herbivore/carnivore, consume autotrophs

Question 2

what do heterotrophs do

Answer 2

take organic material and turn into organic material

Question 3

autotrophs

Answer 3

plants/bacteria

Question 4

what do autotrophs do

Answer 4

take inorganic nutrients (nitrate/phosphate) and turn into organic

Question 5

why do they need micronutrients in large conc

Answer 5

as they come in small doses

Question 6

order of autotrophs/heterotrophs

Answer 6

autotrophs —- heterotrophs (herbivores)—- heterotrophs (carnivores)

Question 7

primary producers

Answer 7

use photosynthesis, inorganic to organic

Question 8

terrestrial plants

Answer 8

large multicellular plants, transfer nutrients/water through leaves

Question 9

marine

Answer 9

plants are small, unicellular, nutrients from seawater

Question 10

what does an autotroph want to be

Answer 10

as small as possible as high surface area to vol ratio

Question 11

when can autotrophs big

Answer 11

lots of nutrients

Question 12

phytoplankton

Answer 12

diatoms, coccolithophores, dinoflagellates, cyanobacteria

Question 13

diatoms

Answer 13

silicon, pillbox shape, transports carbon to deep water, eukaryotic, has oil to combat sinking from heavy silicon

Question 14

dinoflagellates

Answer 14

2 tails, some species are toxic, cause algal bloom, prokaryotes

Question 15

coccolithophores

Answer 15

calcium carbonate shells, transport carbon, heavy, reflect sun

Question 16

cyanobacteria

Answer 16

photosynthetic bacteria, fixes nitrogen, important into oligotrophic areas

Question 17

biomass

Answer 17

how much mass

Question 18

primary production

Answer 18

how much photsynthesis

Question 19

factors limiting growth of phytoplankton

Answer 19

major, secondary

Question 19

major

Answer 19

nutrients/sun

Question 20

secondary

Answer 20

upwelling of nutrients, water movement

Question 21

blooms

Answer 21

occurs when lots of nutrients/sun

Question 22

photic zone

Answer 22

where photosynthesis happens

Question 23

things affecting nutrient conc

Answer 23

grazing, turbidity

Question 24

tropics

Answer 24

lots of sun, not lots of nutrients due to thermocline

Question 25

temperate regions

Answer 25

seasonal, winter (lots of nutrients, limited light), spring (lots of nutrients/light), summer (lots of light, limited nutrients), autumn (some light/nutrients)

Question 26

poles

Answer 26

nutrients all year as no thermocline, productivity high in summer

Question 27

where is highest productivity

Answer 27

estuaries, low in open ocean

Question 28

basin productivity

Answer 28

high at edge low in middle

Question 29

feeding types

Answer 29

grazing, predation, scavenging, filter/deposit feeding

Question 30

zooplankton

Answer 30

foraminifera (single cell), copepods, filter feeders, bacteria
