<h2>Species diversity </h2>
Explanation:
In order to assess the species diversity of a community, one would need to know the number of different species present as well as the relative abundance of the different species
- Species diversity is a function of species richness, the number of species in a given locality and species evenness, the degree to which the relative abundances of species are similar
- The composition of species in a given ecosystem is the result of long lasting evolution
- Each species has adapted to its own niche, which is characterized by certain features (e.g. temperature range, availability of food or light) enabling the species to reproduce and thus maintain its population
- The loss of one species affects many other species and causes imbalance
- As a result, several functions within and of the system are not carried out any more
- Any species that will take over the lost specie's niche will most certainly not replace all of the functions it used to perform

Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.
