-air
-salinity
-soil
-temp
-humidity
-light
-water
-minerals
What are some biotic factors
-Food webs
-Competition
-availability of food

-parasitism
What is species biodiversity
Number of different species and abundance of each species in an area
What is species richness
Number of different species
What is the species evenness
Abundance of each species in an area
What is genetic biodiversity
Variation of alleles within a species or population
What are some benefits of genetic biodiversity
better adaptation to changing environment and more likely to result in individuals resistant to a disease
What can genetic diversity limited by
Small populations which has higher chances of inbreeding
