The amount of energy entering a food chain depends on the
(a) direction of energy flow in the system
(b) efficiency of energy recycling in the system
(c) biomass of carnivores and their efficiency in locating and capturing animal prey
(d) biomass of heterotrophs and their efficiency in transforming plant tissue into animal tissue
(e) biomass of autotrophs and their efficiency in transforming solar energy into chemical energy

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

ans.

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.'
