Mutations are more susceptible to natural selection in large populations, such as the bacterial ones. The bigger the population it is and the shorter the lifespan of the organism, the tougher is the competition between the individuals. So, even a small change, a mutation that enables its holder to have even slightly more chance to survive and reproduce makes a huge difference.
In addition, bacteria have prokaryotic cells that lack the DNA repair mechanisms and they are replicating more often than human cells with eucaryotic cells, which explains the higher rate of mutations in their genomes compared to human ones.
Answer:
Explanation:
A food chain can be described as a series of energy dilutors, the energy that fails to reach the next level being dissipated as heat or movement. Most of the energy contained in the food of animal consumers is used by them during the processes of food collection, digestion and other essential metabolic activity. The overall efficiency of a food chain is therefore rather low and depends mainly on the number of different participants and thus on the length of the food chain. Generally, the greater the complexity of the food web the greater is the efficiency of the system as a whole. The main factors that determine the efficiency of food transfer are temperature, energy, and protein supply. Proteins form the major part of digestible algal and of animal cells; animals depend on receiving an adequate supply with their food because they are unable to synthesize some amino acids.
