Analyze an energy pyramid only about 10 percent of the energy from each level of an energy pyramid is available to the trophic level above it. (the rest is used to power life processes or is lost as heat.) if the primary producers have 10,000 units of stored energy, how much energy would you expect to be transfered to first-level, second-level, and third-level consumers?

The problem tells us that only about 10 percent of the energy of one level is available to the level above it.

So if the primary producers have 10,000 units of stored energy, only 10% would be available for the first level:

For the second-level consumers:

For the third-level consumers:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

compost can be added to topsoil as a:
