Why are ecological pyramids shaped as pyramids?
a) because there is a large decrease in the amount of energy or biomass as you move from one trophic level up to the next?
b) because the movement of energy through the biosphere follows a path similar in shape to a pyramid
c) because decomposers form a wide base of support at the bottom of a food web similar to the base of a pyramid
d) because a pyramid represents a stable building form that is similar to the structure of a stable ecosystem

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
