A scientist uses a computer model to predict that Earth's average temperature will increase between 1.8°C and 3.2°C by the year 2100. The precise increase in temperature depends on people's decisions in the future,

c

explanation:

i think that it is plants

b is the correct answer

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
