How does carbon in animal waste reach the atmospherea. photosynthesis, organic carbon, underground storageb. decomposition, fossil fuel formation, fossil fuel emissionsc. fossil fuel emissions, diffusion, ocean storaged. transportation, diffusion, ocean storage

The correct answer is A. because of photosynthesis Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities (energy transformation).

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."
