Answer 1

accumulate biomass or become fossil fuels so they are not absorbers of co2

Question 2

Answer 2

carbon dioxide uptake of photosynthesis is expected to be equal to the release of co2 due to respiration

Question 3

what happens to photosynthesis when a forest is cut down

Answer 3

drop

Question 4
