Niche

A niche is a job or role in a community. This is my dog, Kaylee. Her niche is being a pet and a friend to my family, friends, and I. I chose this becuse my dog is important to our family and she plays an important role.

Biotic Limiting Factor

This is a tree outside of our middle school. It is a biotic limiting factor. It is a limiting factor because, if it were to be cut down, the animals that live in it would lose their home. Also, it could limit oxygen for humans. The tree is biotic because it is living.
