Organisms that create their own energy (typically from the sun).
What are producers?
100
Examples of this include disease, resources, and predators.
What are density-dependent limiting factors?
100
An interaction that benefits both species
What is mutualism?
100
The gradual change in the structure and competition of a habitat over time.
What is ecological succession?
100
The living factors in an environment (ex. plants and animals)
What are biotic factors?
200
The position an organism occupies in a food web.
What is a trophic level?
200
The maximum population an area can support.
What is the carrying capacity?
200
"To live together"
What is symbiosis?
200
Gradual growth of a ecosystem in a previously uninhabited land.
What is primary succession?
200
The factors that distinguish one biome from another.
What are climate and organisms?
300
Animals that eat only plants
What are primary consumers (herbivores)?
300
This survivorship curves is characterized by an organism having very few offspring but more parental care; low mortality rates early in life.
What is a Type 1 survivorship curve?
300
An interaction that harms one species and benefits the other
What is parasitism?
300
The first stage of succession where plants such as lichens and grasses begin to grow.
What are pioneer species?
300
Multiple species living together in the same area
What is a community?
400
The amount of energy that is retained at each trophic level
What is 10%?
400
A growth curve characterized by a population growing rapidly, then leveling off as resources become limited
What is a logistic growth curve?
400
The type of relationship this shark and remoras have:
What is commensalism?
400
This is typically still present in secondary succession.
What is soil?

The equation for growth rate.
What is r=(b+i)-(d+e)?
500
These birds of paradise have colorful feathers to attract a mate, which is an example of this type of relationship.
What is competition?
500
The 1980 eruption of Mt. St. Helens is an example of this type of succession.
