Vocabulary
Name Three Density Dependent, and Three Density independent limiting factors.
Density Independent: Volcanic eruption, forest fire, landslide, earthquakes, floods, etc.
Name at least 3 symbiotic relationships.
What are mutualism, commensalism, and parasitism? Also predation and herbivory work.
This ecological principle states that no two species can indefinitely occupy the exact same niche in the same place. One will always outcompete the other.
What is the competitive exclusion principle?
The maximum population size of a species that a specific environment can sustainably support over the long term without degrading the habitat.
What is the carrying capacity?
Approximately what percentage of energy is NOT transferred between trophic levels?
What is 90%?
The smallest level of organzation of life.
What is an individual organism?
The interaction where one organism is helped while the other (the host) is harmed.
What is parisitism?
The process by which competing species use the environment differently, allowing them to coexist by dividing limited resources—such as food, space, or time—to minimize competition.
What is niche partitioning?
A diagram showing how energy is transfered between species.
What is an energy pyramid? Food chain is acceptable
All Eastern three-toed salamanders that live in one Burlington wetland in 2026 are considered this.
What is a population?
This organisms, such as Otters and grey wolves, have a disproportionate influence on the functioning of an ecosystem.
What is a keystone species?
Daily Double: What is the difference between intraspecific and interspecific competition?
INTA = between SAME species. INTER = Between DIFFERENT species.
Producers generate 17000 KJ of energy. Estimate how much is available to secondary consumers.
What is 170 KJ?
A bird uses a tree to build a nest and raise her chicks. The tree is neither harmed not helped. This is an example of what type of symbiosis?
What is a commensalism?
This is the entire range of conditions (abiotic) and resources a species can theoretically use in the absence of competition.
What is the fundamental niche?
Environmental pressures that restrict population growth based on its density, impacting high-density populations more severely.
What are density dependent limiting factors?
Diagram that shows how species in an ecosystem are connected by individual food chains.
What is a food web?
What is energy FLOWS and matter is CYCLED?
This term defines how an organism's "job", including its food sources, habitat, and activity patterns, position(s) in the food chain, and resource usage.
What is the ecological niche?
Competition for resource availability can restrict an organism’s use of its environment. As a result, an organism may only use a portion of its fundamental niche. This is called the
What is the realized niche?
