A brown mouse is mated with a white mouse. Brown fur is dominant to white fur. All of their offspring are brown. If two of these brown offspring are mated in the next generation, what fraction of their offspring will be white?

the answer will be a) proteins i believe

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
