(ii) the bacteria have an initial concentration of 1000 cells/cm².
each cell divides once every 30 minutes.
calculate how long it will take for the concentration to become greater than 15 000 cells/cm'.

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 

what is this saying?
