According to the data in the graph, in which year did recycling have the greatest effect on total waste by percentage of waste recycled? Explain.

The year 2008 had a percentage rate of 33.2% meanwhile the rest of the years going back to 1960 had a lower and lower percentage rate the farther back in time you went.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
