Evolution does not happen to
individuals in a few
generations.
Biodiversity increases
chances of survival
Ice blocks sunlight in arctic
regions
An organisms niche allows
for less competition
(everyone has a “job”)
Bio-accumulation: as you
move up a food chain the
amount of toxins/minerals
etc. increase
What are Invasive Species?
What are keystone species?
