animals that eat only plants.

The length of the cell cycle is important because it determines how quickly an organism can multiply. For single-celled organisms, this rate determines how quickly the organism can reproduce new, independent organisms. </span><span>Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms. One reason for this trend is simply that prokaryotic have smaller genomes and not as much DNA to be replicated.</span>

The population age structure is is simply the structure of a population in a given time period by age groups. In order to represent the population age structure in a simple and efficient way, the population pyramid is used. Depending of what type of population is dominant, the pyramid will have different shapes. It can easily show us the trends and type of demographic transition for a particular population. When there high birthrates, the pyramid tends to be widest at the bottom, but when there's low birthrates the pyramid tends to be widening in the middle and upper sections.
