Answer:
2. It decreases genetic diversity only by reducing population size.
Explanation:
Genetic drift is an evolutionary force that works in conjunction with natural selection by changing the allelic frequencies of species over time. It is a consequence of random sampling in reproduction and the loss of some alleles by chance and not by natural selection. Normally there is a loss of the less frequent alleles and a fixation of the most frequent ones, resulting in a decrease in the genetic diversity of the population. They are accentuated in small populations, and result in changes that are not necessarily adaptive.
Answer:
Plants go through a process called photosynthesis that allows them to take carbon dioxide out of the air and turn it into oxygen and energy. The oxygen will later be breathed in by an animal and go through cellular respiration where it will become CO2 again.
