The species that if removed causes a trophic cascade.
What is a Keystone Species?
Energy cannot be created or destroyed, but can be transferred and change forms.
What is the 1st law of thermodynamics?
An species with medium shells develops thicker shells due to selective pressures.
What is directional selection?
A group of individuals of a species living in a particular area.
What is a population?
Something within a system that stabilizes it.
What is a negative feedback loop?
Happens when organisms are given unlimited resources and year round fertility.
What is exponential growth?
When energy is converted from one form to another it loses heat energy.
What is the 2nd law of thermodynamics?
A species with medium height changes to become much shorter in one location, and much taller in another.
What is disruptive selection?
A set of populations of different species living together in a particular area.

What is the edge effect?
Another name for decomposers.
What are detritivores?
A localized extinction of a species.
What is extirpation?
Unrelated species in similar environments develop similar traits due to selective pressures.
What is convergent evolution?
Closely related species living in different environments diverge in their traits due to selective pressures.
