• It includes what it eats, where it lives, and
what it does.

Types of niche:
Fundamental niche

25. niche
FUNDAMENTAL NICHE
can be defined as the range of
environmental conditions in
which each of the species
survives.

26. niche
REALIZED NICHE
can be termed as the range of
environmental conditions in
which a species is really found.

27. Example of
Fundamental and
Realized Niche

niche

32. Red-Tailed Hawk & Barred Owl
•Birds of prey
•Live in forests
on the edge of
fields
•Eat mice and
other rodents
•Nest in trees

33. •No two species can occupy the exact
same niche, because no two species do
the exact same thing.

34. •If they do, or try
to, one will do it
better and the other
will have to change
or become extinct.
