Part A Experimental observation: Nutrient cycling in a temperate forest ecosystem Before manipulating any area of the Hubbard Brook Forest, the researchers spent several years studying the natural watersheds of the forest to try to understand how nutrients move through the various living and nonliving components (reservoirs) of the ecosystem. The diagram below depicts a simplified temperate forest nutrient cycle. The yellow boxes show the main reservoirs of nutrients in the ecosystem. The green arrows show the processes involved in the transfer of nutrients among the reservoirs Note that rainfall results in a net input of nutrients into the ecosystem, whereas erosion and leaching (the loss of soluble nutrients from the soil in groundwater) represent a net loss of nutrients. In Hubbard Brook, as in most temperate forest ecosystems, the amount of nutrients gained and lost through rainfall and erosion or leaching. respectively is small compared to the total amount of nutrients moving around the cycle. consump plants nutrients in rainwater Consumers organic nut n the soil (detritus and decomposers) inorganic nutrients erosion nutrients in in the soil Streams or or leaching groundwater
