Net ecosystem production in a California grassland was -10 g C/m2 in 2006, -5 g C/m2 in 2007, and 2 g C/m2 in 2008. Over the three-year period from 2006 to 2008, did the ecosystem lose carbon or gain carbon?

1: What do trophic relationships illustrate about an ecosystem? 2: About how much of the sun's energy is converted, captured, or fixed by primary producers? 3: Net Primary Production is always lower than Gross Primary Production. What happens to the difference? 4: Does energy flow through an ecosystem or is it recycled? Why? 5: How does climate determine the distribution of ecosystems?
