Definition
Population survival refers to how well a population can withstand changes in its environment over time due to factors such as disease, habitat loss or climate change.
This process causes helpful traits become more common in a population because organisms with these traits have higher survival and reproduction rates than those without them.
Biodiversity refers to the variety of life in a particular habitat or ecosystem. It includes diversity within species (genetic diversity), between species, and of ecosystems.
