3. The match of a
species to a specific
environmental
condition
DEFINITION

4. The relational position
of a species or
population in an
ecosystem.

6. The abiotic or physical
environment is also part of
the niche because it influences
how populations affect, and
are affected by, resources and
enemies
NICHE & ABIOTIC
FACTORS

8.  Hutchinson described
two forms of niche.
 The fundamental niche focused on
the conditions in which a species
could exist with
no ecological interactions.
 The realized niche, in contrast,
considered the population's
existence in the presence of
interactions, or competition.
TYPES

11.  The term was coined by the
naturalist Roswell Hill Johnson but
Joseph Grinnell was probably the
first to use it in a research program
in 1917, in his paper
"The niche relationships of the
California Thrasher".
HISTORY

12.  also called Gause's Principle, states
that when two species compete for
exactly the same resources (thus,
they occupy the same niche),
one is likely to be more successful.
... This principle means: no two
species can sustain coexistence if
they occupy the same niche.
COMPETITIVE
EXCLUSION PRINCIPLE

14. Three parts of a niche include
food type, abiotic conditions,
and behavior.
PARTS OF NICHE

16.  Ecological niches are important for
a given place because they allow
different species to live together,
usually without competition. Each
species knows its position in both
the ecosystem and the food chain.
IMPORTANCE

18.  The natural world is filled with plants
and animals, each with their own special
job or niche.
 A niche is the role played by an organism
in the natural world.
 Animals and plants all have a
special role in making natural
communities work and stay healthy.
 Some animals, like the pileated
woodpecker, are insect eaters.
ROLE

20.  Like other species, the
fundamental niche of humans is
bounded by their biological tolerance of
extremes of environmental conditions.
 Humans also manage
the ecological constraints of their
mutualistic plants and animals such as
agricultural cows, pigs, chickens, and
plant crops.
