What happens if the niches of two species overlap a little?
The species’ population and living is partially affected but it is still maintainable.
What happens if the niches of two species overlap a lot?
One species goes entirely extinct.
How does niche partitioning increase the biodiversity of a community?
Because the animals thrive effectively and there are little to no issues of any kind.
