What are two abiotic factors that might account for the differences in productivity among the land ecosystems in the table?

The factors in an ecosystem that are considered abiotic, or nonliving, are very important to the primary productivity of the ecosystem. Those factors are both chemical and physical, and include light (radiation), temperature, water, atmospheric gases, and soil. Climate generally influences all the abiotic factors.
