Each population depends on other populations in the community for survival. When one population is harmed in the community others are affected. If a fish pond is contaminated with pollution the consumers of the fish will be more greatly affected because of this idea. What is the term to describe this occurrence? 

Biomagnification.

A rabbit population in Wilshire park was established 1 year ago. 25 rabbits were released. The population grew rapidly wreaking havoc on the producer populations. Eventually the rabbit population reached a carrying capacity 2 months ago. Last month a strong storm passed causing multiple rabbit dens to collapse under downed trees. Many rabbits perished in the storm. List 1 density dependent factors and 1 density independent factor. 

Dependent: Producer population as a food source

Independent: Storm
