A food chain can usually sustain no more than six energy transfers before all the energy is used up. And so less energy is transferred at each level of the food chain so the biomass gets smaller.
Hydrophilic heads, hyrdophobic tails. Heads are made of phosphate and the tails are made of lipids.
Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells. In a process known as gene cloning, the host cell's biochemical processes are used to make many copies of the inserted gene and the protein it codes for.
