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
