When two species benefit from interaction with one another
What is mutualism?
The period which human population growth occurred at the greatest rate
What is the modern era? (following the industrial revolution-last 200 years)
The point at which populations can no longer grow any larger
What is carrying capacity?
When a species is no longer present on Earth
What is extinction?
When a one species eats another
What is predation?

What is competition?
Unregulated population growth can be an issue for developing nations do to a lack of this government provided resource
What is infrastructure?
Disease is an example of this type of limiting factor
What is Density Dependent?

What are the Florida Everglades, Hawaii, and coastal California?
Involves one species live on or within another and harming them in the process
What is parasitism?
Japan, China, Canada, and most of Europe are in the 4th stage of demographic transition and therefore are experiencing this population dynamic
What is Decreasing Population?
A volcanic eruption is an example of this type of limiting factor
What is Density Independent?
A species which is a very important to the health of the ecosystem and is therefore used to study the ecosystem as a whole!

What are: Low population size, highly specialized to their niche, habitat destruction, low reproductive rate
What are the 3 provisions of the endangered species act?
1 - provide a list of endangered species
2 - provide protections for those species
3 - prevent the government from undertaking any action that might harm those species
