The effect of geographic factors on the primary production of lacustrine and terrestrial ecosystems

It is shown that, with increasing latitude, the primary production of lakes increasingly lags behind the primary production of land, with a resulting strengthening of the dependence of aquatic ecosystems on allochthonous input of biogenic and organic substances. An ecological model is presented, which allows the primary production of terrestrial and lacustrine ecosystems to be predicted given the geographic coordinates and climatic characteristics.
