Respiration & Photosynthesis

Question 1

Photosynthesis Equation

Answer 1

Solar Energy + 6H2O + 6CO2 —> C6H12O6 + 6O2

Question 2

Respiration Equation

Answer 2

C6H12O6 + O2 —> 6CO2 + 6H2O

Question 3

Photosynthesis

Answer 3

The Primary Producers (bacteria, algae, phytoplankton) use energy captured by Chlorophyll (and ocean water) to convert inorganic carbon to biomass (organic carbon) which is food.

Question 4

Respiration

Answer 4

All organisms consume biomass created from Photosynthesis to make energy through Respiration.

Question 5

Where does Photosynthesis take place?

Answer 5

Euphotic Zone (100 m)

Question 6

Where does Respiration take place?

Answer 6

In all areas

Question 7

How does Photosynthesis and Respiration relate to the Biological Pump?

Answer 7

Biological Pump takes organic carbon fixed by Photosynthesis and transports it into the deep ocean.

All of these organisms that undergo photosynthesis and respiration, as well as their waste products and detritus is categorized as POC. The Biological Pump transfers the POC from the surface ocean to the deep ocean.
