What is a niche?
Normally, when defining a niche we look at 3 sets of parameters:
1) Range of physical factors for survival and reproduction: temperature, humidity, pH, soil, sunlight, etc.
2) Biological factors: predators, prey, parasites, competitors, etc.
3) Behaviour: seasonality, diurnal patterns, movement, social organization, etc.
How is a niche different to a habitat?

How do organisms reduce competition within their own species?
The competitive _________________principle.
If two species compete for________________ limited resources, (___________, _______________) in an ecosystem, they can ________________ ____________________. Either one species
__________________________ the other or one of the species ____________________________
towards another tolerable resource (= competitive ______________________ principle.)
Because of this __________________ species can never fill the ______________________ ecological niche in an ecosystem.
