If 8 is the haploid number of chromosomes in an organism, what is the
organism's diploid number?

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

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 

the missing space is phylum

c. is the correct answer
