ECOLOGICAL NICHE
An ecological niche is..
How an individual organism
''fits'' into an ecosystem
Competition
Birds must find a mate
Must compete with other birds for mates
The niche of an organism includes
where they get their food
my water source
where they find shelter
How i avoid predatore
who they mate whit
My offspring
is based on their adaptations, or traits for survival
1.
I'm not very good at catching ants
2.
I'm pretty good at finding beetles
To avoid competition
1.
Different birds may go after different resources
This avoids niches averlap
Increases chances of survival
To survive
1.
Each organism in an ecosystem has to establish their OWN niche
Most birds build nests in tree branches
But, 2 birds cannot nest on the same branch
Each bird needs to find their own branch to nest on
This is part of establiishing their niches.
2.
when the niches of 2 organisms overlap
competition takes place
