Evaluate the provided diagram, which compares net primary productivity of terestrial biomes. Describe which components were measured to generate the data in the graph.
-
Above and underground biomass are included in the measure of net primary productivity.
-
Net primary productivity is measured by determining the total amount of carbon fixed.
-
Net primary productivity is the amount of carbon fixed minus the amount used during cellular respiration and includes only the aboveground biomass.
-
Net primary productivity is assessed by the determining the amount of carbon used during cellular respiration.

The figure shows different zones present in the ocean. Which of the following statements about marine biomes is true?
-
The benthic zone includes the ocean’s open water and shore.
-
The pelagic realm includes all of the ocean’s open water.
-
The majority of the ocean includes the photic zone.
-
The deepest zone of the ocean is known as the aphotic zone.
-
Corals are able to derive their nutrition from the algae and thus survive in the nutritionally poor water.
-
Corals are able to accumulate calcium carbonate from the algae.
-
They can form coral reefs because of this association.
-
The corals provide protection to the algae.

They trap solar radiation released from the sun as it reaches the Earth’s surface, similar to the glass in a greenhouse.
-
They are found mostly in green houses.
-
These gases are essential for plant growth in a green house.
-
They trap solar radiation, which is converted into thermal radiation on the Earth’s surface of which some is reradiated back into the atmosphere.
