genetic diversity the range of genes within any one species 

ecosystem the variety of different habitats within any given area

abiotic factor- the non living chemical components such as soil PH and temperature 

Biotic factor- all living components and their interactions with each other which may lead to competition between food,space and mates.

  • the distribution of each species in the area at the time

In order to measure biodiversity you need to collect or estimate the number of individuals of each species as…
