Decoupling of Filtering Equations,of dry plant matter produced (net) each year by forests exceeds the total net primary production of the oceans, even though the oceans are more than six times larger in area. The animal biomass in these forests represents 68% of the total found on continental land masses (Whittaker and Likens, 1973).作者: brassy 時間: 2025-3-22 14:48
