Bio 112 April 29th, 2013 More on Ecosystems Food webs -Is a branching food chain with complex trophic interactions -Including decomposes (detritevors) Energy Flow through Ecosystems -from one trophic level to the next. Primary production - are photoautotrophs, capturing energy from the sun. Energy flows from these guys through all other levels. Of course some energy will be lost at each level. -light energy converted to chemical energy by autorophs during a given time period. -Gross primary production is the total primary production. -Net primary production is GPP minus energy used by producers (respiration)-only this is available to consumers. NPP is more important then GPP. Secondary production
