***NAME THAT TUNE***
An environmental factor that limits a population's growth is called a limiting factor. A factor that can affect population sizes are natural disasters such as volcanic eruptions.

The three types of ecological pyramids are ?
What is energy pyramid, biomass pyramid and numbers pyramid?

***NAME THAT TUNE***
Fertilizers used on land contain phosphate and nitrogen that become runoff. This creates algal blooms, which leads to "dead zones" and disrupts the natural balance in that ecosystem. This is called what?
What is eutrophication?
