ecosystem?
What is meant by

Why are there so
many different
species on earth?
Due to the evolution of related

If one
organism in
the food
web
decreases,
then others
will either
increase or
decrease
What happens to an
ecosystem when
biodiversity decreases?
Ecosystem stability decreases!
Stability – the ability of the different
populations of organisms to survive an
environmental change.
How does great
biodiversity maintain
ecosystem stability?
In an ecosystem with
great biodiversity
If one organism dies
off, another may step
in and take over its
NICHE!
Which ecosystem has
greater stability?
Rainforest or Grassland
 The
forest has greater stability
because it has greater
biodiversity!
How is biodiversity lost?
 Natural disaster & human
activities
Why is biodiversity
important to us?
 It
ensures the stability of an
ecosystem.
 Biodiversity has provided us
with medicines, shelter, &
