An energy pyramid illustrates that energy in the form of heat is lost to the surrounding as it is passed from one organism to the next. In an energy pyramid energy is passed from one trophic level to the next, however, only ten percent of the energy in a given trophic level is passed to the next, as most of the energy is lost inform of heat to the surroundings.

I not sure but i think it is 4
After the fossils are buried in the mud the soft tissues start to decompose rapidly. Leaving only the hard shells or bones of the animal. With time, sediment starts to build up on the top and then hardens into rock. The bones then start to decay, minerals start to enter and then end up replacing the organic material cell by cell in a process that is known as "petrification." So the answer you are looking for is B, Mud can prevent oxygen from reaching the dead organism.
<span>Alanine is one of the simplest amino acids in terms of molecular structure and one of the most widely found in protein. In humans, the L-isomer, which is the only form that is involved in protein synthesis, is one of the 20 standard amino acids required for normal functioning. Alanine is classified as a nonpolar amino acid.</span>
