The type of succession that occurs in an area with existing soil
Secondary Succession
When two species benefit from interacting with one another
Mutualism
The Biome with highest biodiversity. Located near the equator
Tropical Rainforest
This is the most significant reason that biodiversity is important to the environment
High biodiversity makes ecosystems more stable
The type of succession that occurs in areas with no existing soil
Primary Succession
When one species eats another
Predation
The two factors that determine which Biome exists in an area
Temperature and Precipitation
When a population has grown to its maximum and cannot become any larger
Carrying Capacity
The type of succession that may proceed after a farm is abandoned or a wildfire occurs
Secondary Succession
A relationship that harms both organisms
Competition
The process that keeps the earth warmer than it would be by trapping heat energy before it reflects back into space
The Greenhouse Effect
Wolves are an example of this kind of species which is important to the function of the environment
Keystone Species
The type of succession that would follow a volcanic eruption or the retreat of glaciers
Primary Succession
One species lives within another and harms them in the process
Parasitism
The greenhouse gas of most concern to climate scientists
CO2 (carbon Dioxide)
A non native species introduced by humans that out-competes or harms native species
Invasive Species
A species that is the first to colonize an area (moss and lichen are the most common)
Pioneer Species
A relationship where a primary consumer eats a producer
Herbivory
The process causing the largest release of greenhouse gasses
Humans burning fossil fuels
Guyana is experiencing this population dynamic

Exponential Growth (High birthrate low death rate)
What an ecosystem is called when has reached its maximum and most stable state
Climax Community
A relationship that benefits one organism and neither benefits nor harms the other
Commensalism
What are the top two ways humans can reduce their ecological footprint
Eat less meat and dairy, have fewer children
The population dynamic that this country is experiencing

Stable population
These are the 3 statutes established by the Endangered Species Act (ESA)
1. Create an endangered species list
2. Provide protection for the species listed
3. Prevent the federal government from taking any action that will harm these species
