Responses
The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
The plankton as a carbon sink and as a carbon source in the area will be less than expected.
The plankton as a carbon sink and as a carbon source in the area will be less than expected.
The plankton as a carbon sink will be less than expected, but the plankton as a carbon source will be greater than expected.
The plankton as a carbon sink will be less than expected, but the plankton as a carbon source will be greater than expected.
The plankton as a carbon sink will be greater than expected, but the plankton as a carbon source will be less than expected.
Responses
The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
The plankton as a carbon sink and as a carbon source in the area will be less than expected.
The plankton as a carbon sink and as a carbon source in the area will be less than expected.
The plankton as a carbon sink will be less than expected, but the plankton as a carbon source will be greater than expected.
The plankton as a carbon sink will be less than expected, but the plankton as a carbon source will be greater than expected.
The plankton as a carbon sink will be greater than expected, but the plankton as a carbon source will be less than expected.
The correct conclusion is: The plankton as a carbon sink and as a carbon source in the area will be less than expected.
A significant decrease in phytoplankton population would mean that there is less biomass available to absorb carbon dioxide (carbon sink) and also less organic material available for other organisms (carbon source).
