The diversity of sexually reproducing species is a result of the fact that a) gene pools change over time (by selection and genetic drift) and that b) reproductive isolation occurs, leading to the inability of the descendants of formerly interbreeding subpopulations to interbreed (speciation).

Extinction is the permanent removal of a species which decreases bio-diversity. Bio-diversity is measured in two fashions # of species and # of members/species these two factors together make up a regions bio diversity, therefore with the removal of a species the regions bio-diversity decreases.
Social factors contribute to diversity because people have different backgrounds.Individual factors contribute to diversity because people have different personalities.

Meiosis accounts for species diversity. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes. Meiosis is responsible for producing gametes or sex cells.

Diversity refers to the presence of a variety of differences within a group, such as differences in race, gender, abilities, etc. Difference, on the other hand, simply means a variation or distinction between two or more entities, without necessarily implying a broader range of diversity. In essence, diversity encompasses the broader spectrum of differences that exist, while difference is more specific and can refer to any distinction between two things.
Sexual reproduction mixes the genetic inheritance for each generation;Different environmental pressures on different species - only those species that have the best characteristics to survive the environmental pressures will survive long enough to reproduce and leave their genes for the next generation.

There are two factors that need to be taken into account when it comes to risk assessment. First of all, there is the magnitude of the potential loss. Secondly, there is the probability that the loss will occur.
