Question 2

dominant carbon form in water depends on ______

Answer 2

pH of water

Question 3

more dissolved _______ in water = greater buffering capacity

Answer 3

bicarbonate

Question 4

increased CO2 in atmosphere = increases ____ of lake

Answer 4

acidity

Question 5

explain the carbon buffering system in water
______ <-> ______ <-> ______

Answer 5

carbonic acid <-> bicarbonate <-> carbonate

Question 6

organic carbon can be in two forms

Answer 6

particulate and dissolved

Question 7

particulate organic carbon:
- can be _____ or ______
- made of _______ material
- helpful to heterotrophs because

Answer 7

fine or coarse
living or dead
food source

Question 8

dissolved organic carbon: two categories

Answer 8

humic and non-humic

Question 9

process that forms organic carbon in ecosystem

Answer 9

photosynthesis

Question 10

process that breaksdown organic carbon in ecosystem

Answer 10

respiration

Question 11

heterotrophs can create available organic carbon for other heterotrophs. how?

Answer 11

big hetero eats food and breaks it down into smaller bits of carbon. smaller invertebrates eat that small carbon crumbs and those carbon crumbs get further broken down into itty bitty crumbs. now microbes can eat those itty bitty crumbs…..

Question 12

process of inorganic carbon (CO2) to organic carbon

Answer 12

photosynthesis

Question 13

process of organic carbon to inorganic carbon (CO2)

Answer 13

respiration
