Given a trait phenotype determined by a single autosomal locus with two alleles, where the mode of inheritance is reduced-penetrant recessive with no phenocopy, how many possible genotypes can an unaffected individual (who has not been genotyped) have at the trait locus

i think that it is plants

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
