How Is The Carbon Cycle Regulated?

Question 1

Photosynthesis

Answer 1

Phytoplankton sequester CO2 = From atmosphere to ocean store

Terrestrial (plants) sequester + release back to atmosphere via respiration + decomp

Tropical rainforest = High photosynthesis

Desert = Spare vegetation so little photosynthesis

Question 2

Different Ecosystems

Answer 2

The rate at which plants produce biomass is called primary productivity

Tropical rainforest = high primary productivity

Tundra = Low primary productivity as cold + dry
