NICHE

• A niche is an organism’s role (job) in the ecosystem

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

Fundamental niche

Realized niche

nicheFUNDAMENTAL

NICHE

can be defined as the range of environmental conditions in which each of the species survives.

niche

REALIZED NICHE

can be termed as the range of

environmental conditions in which a

species is really found.

Example of Fundamental and

Realized Niche

nicheexample:

raccoons

naturally live in forests and eats insects, fruits, and other small creaturesFundamental

niche

nicheexample:

encroachment by humans

changes their habitat to an

urban environment

and they start to live off of

our trash and other wasteRealized niche

Examples of Niche….

A beaver’s niche in the ecosystem includes:

• cutting down trees• building a dam to flood an area and make a pond• building a lodge to live in• raising a family of beavers• chewing bark and wood

niche

Red-Tailed Hawk & Barred Owl•Birds of prey

•Live in forests on the edge of fields

•Eat mice and other rodents

•Nest in trees

hawkBarred owl

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

•If they do, or try to, one will

do it better and the other will have to change or become extinct.
