Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A anda, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight. a.) If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F1 progeny

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
