1. Competition
Competition can occur between animals of the same species or between different species. Variations between the animals is a big factor on who will win. The other animal must move adapt to this situation to avoid or reduce competition they alter their niche .Ex. Mule deer and white tail deer. Cougar and lynx can live in the same niche. How?

2. warbler
Pg 18
These warbler all live in the same tree but they not share their niche so they not compete with each other.

3. Niches
There are two types of niches. They are the broad niche and a narrow niche. A broad niche is vast in land but small in the different types of animals that live in it. Northern Canada is a broad niche. These animals can live here year around so they adapt to seasonal changes. Hot summers to drastic cold in the winter they have adaptations which allow to survive. These types of animals are called Generalists. Generalists can survive over large areas.

4. Niches
A narrow niche is much different than a broad niche. You would find a narrow niche in tropical area where seasons do not change. The amount of different types of species in these niches is vast, but they can not tolerate a large area .It can be so small a couple of centimeters on tree branch could cause this species to die. These species are called specialist. This specialization allows many animals to live in a small area.
(Discuss Trap of specialization)

5. Symbiotic Relationships
We need to have communities of micro organisms to help us survive( digestive system) These micro-organisms help us in digestion in food and we supply them with a place to live. This a mutualism relationship because we both benefit from it. We also have commensalism relationships where one species benefits and the other does not. Parasitism is where one species benefits and the other is harmed.
